This summer, nine MIT students worked across the Middle East through the MISTI Arab World Program. 

“At MISTI Arab World, the most impactful learning occurs when students venture beyond their comfort zones and experience the richness of a dynamic region,” says Maye Elqasem, program administrator of MISTI Arab World. “Our students return not only with new technical and professional capabilities, but also with a greater sense of self, resilience, and global awareness.” 

Since it launched in 2014, more than 200 students have participated in MISTI Arab World, providing them with essential international perspectives while connecting them to meaningful work.

“Each internship is a bridge connecting MIT to the region, bridging theory with implementation,” Elqasem says.

Seeing the Middle East for herself

One of this year’s students was junior Khadiza Rahman, a chemical and biological engineering major. Born in Bangladesh and raised in Queens, New York, Rahman hadn’t left the United States in over a decade. She spent 10 weeks in Casablanca, Morocco, working at the OCP Group, the world’s largest phosphate mining company.

Rahman’s interest in the region was sparked last year as a student in class 21H.161 (The Modern Middle East), a course taught by Pouya Alimagham.

“It was an eye-opening class. Through scholarly works, my opinion of the region changed and I realized biases that I held. It made me want to go to the Middle East to see it for myself,” she says.

Her internship was with Pixel, a sustainability startup incubated at OCP through Le Mouvement, an internal initiative where employees pitch business ideas at a demo day (similar to those often hosted at MIT) and then receive seed funding and the workday space to launch them.

“Pixel aims to create an integrated system for helping farmers around the world get better crop results,” Rahman explains.

“I essentially combined genomic, climate, and environmental data to create a model to provide actionable forecasts that could be used for policy decisions. For example, if we were to receive the climate data, it could predict the biological richness and diversity of the soil.”

The experience reinforced her interest in engineering and management while also challenging and inspiring her in unexpected ways. For example,  her coworkers began each day with tea and conversation. This “human-centered approach” is something she hopes to carry into her own career.

For housing, Rahman was paired with another woman from MIT, and MISTI and helped them find an apartment in Casablanca’s financial center. “At the beginning, I was a little afraid to venture outside my comfortable apartment, but the real experiences you get from MISTI come from going out and exploring,” she says.

One highlight was a hike in the Ourika Valley outside Marrakech. “I wasn’t sure if I was physically prepared for a long hike,” she admits. “We climbed a really high mountain in the Ourika Valley. It was scary at first, but it turned into an amazing experience, with incredible views of the mountain range and waterfalls. I stood there at the peak and realized that I should never have doubted myself in the first place.” 

That’s a lesson that Rahman says she’ll remember amidst whatever challenges her future career throws her way. 

Harnessing AI to improve the passenger experience

MIT senior Amitoj Singh, a computer science and electrical engineering major, joined MISTI after taking four courses on Middle Eastern history and politics. His internship with Abu Dhabi Airports combined his regional interest with his technical expertise and gave him a new sense of direction.

Raised near Los Angeles, Singh had never left North America. He first connected with MISTI in January 2025 through doing a short internship in a startup in the MITdesignX accelerator in Dubai. After helping a fintech company streamline United Arab Emirates mortgage applications using artificial intelligence, he sought out another, longer work opportunity.  

Elqasem worked closely with him to finalize a placement with Abu Dhabi Airports Smart Airports Initiative.

“My skill set fit what the airport was looking for, and it turned out to be a perfect match,” Singh says.

MISTI also paired him with mentor Rajeet Sampat, a 2017-18 MIT Sloan Fellow and vice president of strategy at Abu Dhabi Airports.

“My day-to-day work in the office involved working on an independent use-case, which is developing an application of machine learning and AI software to perform predictive data analysis at Abu Dhabi Airports,” Singh says.

The Smart Airports Initiative uses biometrics and AI to streamline travel — from facial recognition that replaces stressfully long check-ins to real-time virtual simulations of airport operations.

“For example, if an airline experiences an unexpected flight delay, air traffic controllers would be able to seamlessly visit their virtual environment dashboard to make an immediate decision about which terminals the aircraft can park at when it arrives, eliminating further delays,” Singh explains.

Despite the fact that he was directing various airport divisions, Sampat took his mentoring responsibility seriously, meeting with Singh weekly, helping him to clarify strengths and identify aspects of work that could bring long-term fulfillment.

“Very inclusive, collaborative, and startup-inspired,” is how Sampat describes his office’s culture.

For Singh, the most valuable lesson was learning to work in a global environment with colleagues from many backgrounds and specialties. “When I got stuck, there was always someone to ask for help in finding a solution,” he says. “They were highly welcoming and collaborative.”

Singh is still exploring career paths, but discovered he seeks work that connects him to others and “ultimately be able to use college as a journey that will eventually help me to give back to others more.”

Sampat offered him advice: “You can be somebody who enjoys coding and putting things together, but there’s another side of things in the corporate world. I need people with strengths like you to also strategize and lead the way.” To push him, Sampat invited Singh to join the AI team in shaping future strategy. “That is how a coder turns into a leader,” he says.

We’ve known since ancient times that physical activity can prevent and treat a broad range of mental and physical illnesses. But today, exercise is not a central focus of modern health-care systems. Why? This is the motivating question behind MIT’s class STS.041/PE&W.0537 (Exercise is Medicine: From Ancient Civilizations to Modern Healthcare Systems) — a collaboration between the MIT Program in Science, Technology, and Society (STS) and the Department of Athletics, Physical Education, and Recreation (DAPER).

Going beyond the MIT tradition of hands-on learning, Exercise is Medicine (EIM) offers full-body experiential education, combining readings, lectures, and physical activity at the Zesiger Center and on MIT’s playing fields. Students investigate topics including barriers to exercise, loneliness as a public health issue, and social determinants of health through partner acrobatics, broomball, and sailing. During midterm week, they reflect on the mental health impact of activities, including meditation and pickleball. They also learn about the principles of traditional Chinese medicine through Qigong.

Co-taught by professors Jennifer Light and Carrie Moore, in addition to other DAPER instructors, EIM was first offered in spring 2024 for 20 undergraduates. Students from every major are invited to enroll — the next offering filled quickly, doubling in size to 40 students, with a long waitlist.

Exercise is Medicine is one of three courses Light and Moore offer as part of the MIT Project on Embodied Education, launched in 2022. Professor Light was eager to create an academic class where students spent at least 50 percent of their learning time out of their seats doing a physical activity that reinforced the academic objectives she was presenting.

“I was developing a new research project on the ancient wisdom and modern science of movement and learning, and was looking to develop courses that put this method into practice. Through Anthony Grant, athletic director and head of the DAPER, I connected with Carrie. We are having so much fun collaborating; one course quickly became two, and now three,” says Light.

History of medicine and health systems courses have long been a staple of the STS program. In EIM, students visit with MIT Chief Health Officer Cecelia Stuopis, who offers insight into the place of exercise in health care throughout the history of the Institute. Discussions also include the economic factors that may impact ideas and innovations from STEM fields.

The partnership with DAPER helps students deepen their understanding of the readings and lectures and, Light hopes, sets them up to find ways to integrate movement into their lives after the semester’s end. Moore adds, “This course allows students to reflect on the impact of movement on their cognition — experiencing increases in motivation, mood, focus, and community, as well as improved retention of content by engaging more parts of the brain.”

“DAPER instructors have an amazing ability to make so many physical activities accessible at the beginner level, and students come away from the course appreciating new activities they can do while on campus or as they move into the real world,” says Light.

Nathan Kim, a senior in Course 15 (Management), says, “When I think of my MIT education, I mostly think about problem sets and studying for exams. Learning is initially thought of as a cognitive output and performance. Even in project-based classes, there’s little attention to the body’s role in comprehension. However, this course broke that mold. Instead of treating the body as separate from the mind, it treated it as an essential partner in learning.”

“I love that this class stretches students’ minds and bodies at the same time. They get to learn serious academic content, try all sorts of new physical activities, and do so in a context that aims to make what they’re learning personally relevant to the remainder of their time in college and life beyond. The idea that their bodies aren’t just there to transport their heads around campus — but can be resources for academic learning — is a revelation to pretty much everyone in the class,” says Light.

Emily Zhou, a senior in computer science and engineering, adds, “After reading about the role of team sports in reducing loneliness and improving mental health, I didn’t expect the connection to feel so immediate. But the moment I was slipping and falling on the ice [while playing broomball] with my teammates, some of whom I had never met before, it clicked for me. As we coordinated strategies and cheered together every time we made a goal, I gained a deeper understanding of the reading, and why collective physical activity builds meaningful connections. I could genuinely feel how community forms differently when I’m trusting people with my physical body.”

“It’s a unique and enriching experience for the students to have experiential learning be a component of the class. Not only does it create shared memories of something special that we hope they will have for a lifetime, but it’s also a lot of fun. It frees their minds from to-do lists and other tasks and it gives them extra energy throughout the day. Their brains may be tired at the end of the day, but not their bodies,” says Moore.

The class also fulfills MIT’s General Institute Requirements. Students who successfully complete the class earn HASS credit and two Physical Education and Wellness points. 

Earlier this year, Light and Moore presented findings from their ongoing class collaborations at the National Association for Kinesiology in Higher Education conference. The pair showcased how they connected the academic side of MIT with the activity side of campus, with the hopes of inspiring others to follow in a similar direction. They’re also working to help other MIT instructors bridge the two sides of Massachusetts Avenue.

“Professor Light and I have created a synergy of what education could be,” says Moore. “The model created works at MIT and is received well by our students, so we want to help faculty reshape the way they teach to enrich learning and the student experience. We hope that when our students become leaders in their careers, they will share the lessons they learned in our classes with their colleagues. If they do so, then we’ve done our job.”

MIT professors Michael McDonald and Kristala Prather embody a form of mentorship defined not only by technical expertise, but by care. They remind us that the most lasting academic guidance is not only about advancing research, but about nurturing their students along the way.

For McDonald’s students, his presence is one of deep empathy and steady support. They describe him as fully committed to their well-being and success — someone whose influence reaches beyond academics to the heart of what it means to feel valued in a community. Prather is celebrated for the way she invests in her mentees beyond formal advising, offering guidance and encouragement that helps them chart paths forward with confidence.

Together, they create spaces where students are affirmed as individuals as well as scholars. 

Professors McDonald and Prather are members of the 2023–25 Committed to Caring cohort, recognized for their dedication to fostering growth, resilience, and belonging across MIT.

Michael McDonald: Empathetic, dedicated, and deeply understanding

Michael McDonald is an associate professor of physics at the MIT Kavli Institute for Astrophysics and Space Research. His research focuses on the evolution of galaxies and clusters of galaxies, and the role that environment plays in dictating this evolution. 

A shining example of an empathetic and caring advisor, McDonald supports his students, fostering an environment where they can overcome challenges and grow with confidence. One of his students says that “if one of his research or class students is progressing slowly or otherwise struggling, he treats them with respect, care, and understanding, enabling them to maintain confidence and succeed.”

McDonald also goes above and beyond in offering help and guidance, never expecting thanks, praise, or commendation. A student expressed, “he does not need to be asked to advocate for students experiencing personal or academic challenges. He does not need to be asked to improve graduate student education and well-being at MIT. He does not need to be asked to care for students who may otherwise be left behind.”

When asked to describe his advising style, McDonald shared the mantra “we’re humans first, scientists second." He models his commitment to this idea, prioritizing balance for himself while also ensuring that his students feel happy and fulfilled. “If I’m not doing well, or am unhappy with my own work/life balance, then I’m not going to be a very good or understanding advisor,” McDonald says.

Students are quick to identify McDonald as a dedicated and deeply understanding teacher and mentor. “Mike was consistently engaging, humble, and kind, both bolstering our love of astrophysics and making us feel welcome and supported,” one advisee commended.

On top of weekly meetings, he conducts separate check-ins with his students on a semesterly basis to track not only their accomplishments and progress toward their personal goals, but also to evaluate his own mentoring and identify areas of improvement.

McDonald “thinks deeply and often about the long-term trajectory of his advisees, how they will fit into the modern research landscape, and helps them to develop professional and personal support networks that will help them succeed and thrive.”

McDonald feels that projects should be so much fun that they do not feel like work. To this end, he spends a lot of time developing and fleshing out a wide variety of research projects. When he takes on a new student, he presents them with five to 10 possible projects that they could lead, and works with them to find the one that is best matched to the student’s interests and abilities. 

“This is a lot of work on my end — and many of these projects never see the light of day — but I think it leads to better outcomes and happier group members,” McDonald says. One of the most impactful qualities in a mentor and supervisor is how they deal with challenges and failures, both their own and those of others, which McDonald does very effectively.

One nominator sums up McDonald’s character, writing that “Michael McDonald fully embodies the spirit of Committed to Caring as a teacher, advisor, counselor, and role model for the MIT community. He consistently impacts the lives of his students, mentees, and the physics community as a whole, encouraging us to be the best versions of ourselves while striving to be a better mentor, father, and friend.”

Kristala Prather: Meaningful support and departmental impact

Kristala Prather is the Arthur Dehon Little Professor of Chemical Engineering and is the head of the Department of Chemical Engineering. Her research involves the design and assembly of novel pathways for biological synthesis, enhancement of enzyme activity and control of metabolic flux, and bioprocess engineering and design.

Prather has proven to be a dedicated mentor and role model for her students, particularly those from underrepresented backgrounds. One nominator mentions that as an immigrant woman of color with no prior exposure to academia before coming to MIT, Prather’s guidance has been extremely important for her. Prather has pointed the nominator to resources that she didn't know existed, and helped her navigate U.S. and academic norms that she was not well-versed in. 

“As an international student navigating two new cultures (that of the U.S. as well as that of academia), it is easy to feel inadequate, confused, frustrated, or undeserving,” the student stated. Prather’s level of mentorship may not be easy to find, and it is extremely important to the success of all students, especially to marginalized students. 

Prather actively listens to her students’ concerns and helps them to identify their areas of academic improvement with regard to their desired career path. She consistently creates a comfortable space for authentic conversations where mentees feel supported both professionally and personally. Through her deep caring, advisees feel a sense of belonging and worthiness in academia.

“I treat everyone fairly, which is not the same as treating everyone the same,” Prather says. This is Prather’s way of acknowledging the reality that each individual comes as a unique person; different people need different advising approaches. The goal is to get everyone to the same endpoint, irrespective of where they start.

In addition to the meaningful support which Prather provides her students, she has also dedicated extra time to mentoring. One nominator explained that Prather has been known to meet with individual students in the department to check in on their progress and help them navigate academia. She also works closely with the Office of Graduate Education to connect students from disadvantaged backgrounds to resources that will help them succeed. In the department, she is known to be a trustworthy and caring mentor. 

Since much of Prather’s mentoring goes beyond her official duties, this work can easily be overlooked. It is clear that she has deliberately dedicated extra time to help students, adding to her numerous commitments and official positions both inside and outside of the department. Through their nominations, students called for the recognition of Prather’s mentorship, stating that it  “has meaningfully impacted so many in the department.”

Professor Ioannis V. Yannas SM ’59, a physical chemist and engineer known for the invention of artificial skin for the treatment of severe burns, and a longtime member of the MIT faculty, died on Oct. 19 at the age of 90.

“Professor Yannas was a beloved and distinguished colleague, teacher, and mentor. The impact of his inventions, and his legacy on the field of bioengineering was immense,” says John Hart, the Class of 1922 Professor and head of the Department of Mechanical Engineering. 

Yannas, known to friends and colleagues as Yanni, held appointments in the MIT Department of Mechanical Engineering and the Harvard-MIT Program in Health Sciences and Technology. His principal research interest throughout his career was the process of induced organ regeneration used to replace organs that are either severely injured or terminally diseased. His work also advanced the clinical use of collagen tubes to treat peripheral nerve injuries.

In 1969, when Yannas approached the late John Burke of Massachusetts General Hospital to collaborate, Burke took him on a tour of a children’s burn unit. “There was a great deal of human misery that was confronting me, and I felt I had to do something about it,” said Yannas in later interviews. In 1981, the pair announced their success: an amalgam of a silicone outer sheet over a scaffolding of molecular material drawn from cow tendon and shark cartilage. Offering protection from infection and dehydration, the scaffolding enabled healthy skin cells to grow. Their discovery would be transformative for the treatment of burn victims.

Their artificial skin, patented and now manufactured as Integra, is still widely used on patients with severe and extensive burns, and for other applications including some types of plastic surgery and the treatment of chronic skin wounds commonly suffered by people with diabetes. The groundbreaking advance, which was later recognized as the first example of organ regeneration in adults, had previously been considered impossible.

“Yanni’s boldness in attacking a wide array of medical problems, including spinal cord transection, in his investigations of applications of collagen-based implants, inspired others, including myself, to work toward solutions to devastating conditions such as blindness, stroke, and spinal cord injury,” says Myron Spector, professor emeritus of orthopedic surgery (biomaterials) at Massachusetts General Brigham and Harvard Medical School, and an affiliate of the Harvard-MIT Program in Health Sciences and Technology. Yannas and Spector created several MIT courses together, including 2.79 (Biomaterial-Tissue Interactions).

“As we were talking about the content [for 2.79], Yanni proposed that we codify the cell behavior underlying the tissue response to implants,” explains Spector. “Within a short time, we laid out the plan for ‘unit cell processes’ to offer students a code to decipher the often inconceivably complex cellular processes that not only underlie the tissue response to implants, but that can guide the selection of the tools necessary to engineer medical devices and reveal their targets for treatment. This was all Yanni, taking a fundamental concept, the control volume used in chemical engineering to analyze systems, and applying it to cellular processes in the human body. I since use UCPs myself all the time.”

As a colleague serving as a collaborator in teaching and in research, Spector says Yannas was eager to help and to learn, bold in his thinking, smart in his choices, able to keep his eye on the goal, respectful of students as well as faculty and other colleagues, and selfless. “These are just the traits that we teach our students to look for when seeking the collaborators who are so necessary in science and engineering.”

Yannas was born on April 14, 1935, in Athens, Greece, where he completed his high school education at Athens College. He received a BA in chemistry at Harvard College in 1957, followed by an MS in chemical engineering from MIT in 1959. After a period of industrial research on polymers at W. R. Grace & Co., in Cambridge, Massachusetts, he attended Princeton University, where he completed an MS degree in 1965 and a PhD in 1966, both in physical chemistry. Yannas joined the MIT faculty immediately thereafter and remained at the Institute for the next 59 years until his passing.

For his discoveries in organ regeneration, Yannas was elected member of the National Academy of Medicine (1987), the National Inventors Hall of Fame (2015), and the National Academy of Engineering (2017). He was also elected Fellow of the American Institute of Medical and Biomedical Engineering.

Further, he was the recipient of many prestigious awards including the Society for Biomaterials Founders Award (1982) and the Society’s Clemson Award for Applied Science and Engineering (1992). He was an author of numerous journal articles, and the sole author of the influential book, “Tissue and Organ Regeneration in Adults.”

Yannas’ work, and 2015 induction into the National Inventors Hall of Fame, was the subject of “Hope Regenerated,” a video produced by the MIT Department of Mechanical Engineering. The film chronicles the development of Integra, which was initially characterized as a “failed experiment” but became a life-saving discovery that launched a new field of regenerative medicine.

“My father's relationship with MIT was deeply meaningful to him,” says Tania Yannas Kluzak. “He regarded MIT as the ideal partner in his life's work — pioneering lifesaving research in organ regeneration.”

Yannas was predeceased by his brother, Pavlos. He is survived by his two children, Tania Kluzak and her husband Gordon, and Alexi Yannas and his wife Maria; his grandchildren — Alexandra, Marina, Sophia, Philippos, and Nefeli; his sister, Elizabeth Sitinas; and many loving relatives and friends. A celebration of life will be announced at a later date. 

How can you use science to build a better gingerbread house?

That was something Miranda Schwacke spent a lot of time thinking about. The MIT graduate student in the Department of Materials Science and Engineering (DMSE) is part of Kitchen Matters, a group of grad students who use food and kitchen tools to explain scientific concepts through short videos and outreach events. Past topics included why chocolate “seizes,” or becomes difficult to work with when melting (spoiler: water gets in), and how to make isomalt, the sugar glass that stunt performers jump through in action movies.

Two years ago, when the group was making a video on how to build a structurally sound gingerbread house, Schwacke scoured cookbooks for a variable that would produce the most dramatic difference in the cookies.

“I was reading about what determines the texture of cookies, and then tried several recipes in my kitchen until I got two gingerbread recipes that I was happy with,” Schwacke says.

She focused on butter, which contains water that turns to steam at high baking temperatures, creating air pockets in cookies. Schwacke predicted that decreasing the amount of butter would yield denser gingerbread, strong enough to hold together as a house.

“This hypothesis is an example of how changing the structure can influence the properties and performance of material,” Schwacke said in the eight-minute video.

That same curiosity about materials properties and performance drives her research on the high energy cost of computing, especially for artificial intelligence. Schwacke develops new materials and devices for neuromorphic computing, which mimics the brain by processing and storing information in the same place. She studies electrochemical ionic synapses — tiny devices that can be “tuned” to adjust conductivity, much like neurons strengthening or weakening connections in the brain.

“If you look at AI in particular — to train these really large models — that consumes a lot of energy. And if you compare that to the amount of energy that we consume as humans when we’re learning things, the brain consumes a lot less energy,” Schwacke says. “That’s what led to this idea to find more brain-inspired, energy-efficient ways of doing AI.”

Her advisor, Bilge Yildiz, underscores the point: One reason the brain is so efficient is that data doesn’t need to be moved back and forth.

“In the brain, the connections between our neurons, called synapses, are where we process information. Signal transmission is there. It is processed, programmed, and also stored in the same place,” says Yildiz, the Breene M. Kerr (1951) Professor in the Department of Nuclear Science and Engineering and DMSE. Schwacke’s devices aim to replicate that efficiency.

Scientific roots

The daughter of a marine biologist mom and an electrical engineer dad, Schwacke was immersed in science from a young age. Science was “always a part of how I understood the world.”

“I was obsessed with dinosaurs. I wanted to be a paleontologist when I grew up,” she says. But her interests broadened. At her middle school in Charleston, South Carolina, she joined a FIRST Lego League robotics competition, building robots to complete tasks like pushing or pulling objects. “My parents, my dad especially, got very involved in the school team and helping us design and build our little robot for the competition.”

Her mother, meanwhile, studied how dolphin populations are affected by pollution for the National Oceanic and Atmospheric Administration. That had a lasting impact.

“That was an example of how science can be used to understand the world, and also to figure out how we can improve the world,” Schwacke says. “And that’s what I’ve always wanted to do with science.”

Her interest in materials science came later, in her high school magnet program. There, she was introduced to the interdisciplinary subject, a blend of physics, chemistry, and engineering that studies the structure and properties of materials and uses that knowledge to design new ones.

“I always liked that it goes from this very basic science, where we’re studying how atoms are ordering, all the way up to these solid materials that we interact with in our everyday lives — and how that gives them their properties that we can see and play with,” Schwacke says.

As a senior, she participated in a research program with a thesis project on dye-sensitized solar cells, a low-cost, lightweight solar technology that uses dye molecules to absorb light and generate electricity.

“What drove me was really understanding, this is how we go from light to energy that we can use — and also seeing how this could help us with having more renewable energy sources,” Schwacke says.

After high school, she headed across the country to Caltech. “I wanted to try a totally new place,” she says, where she studied materials science, including nanostructured materials thousands of times thinner than a human hair. She focused on materials properties and microstructure — the tiny internal structure that governs how materials behave — which led her to electrochemical systems like batteries and fuel cells.

AI energy challenge

At MIT, she continued exploring energy technologies. She met Yildiz during a Zoom meeting in her first year of graduate school, in fall 2020, when the campus was still operating under strict Covid-19 protocols. Yildiz’s lab studies how charged atoms, or ions, move through materials in technologies like fuel cells, batteries, and electrolyzers.

The lab’s research into brain-inspired computing fired Schwacke’s imagination, but she was equally drawn to Yildiz’s way of talking about science.

“It wasn’t based on jargon and emphasized a very basic understanding of what was going on — that ions are going here, and electrons are going here — to understand fundamentally what’s happening in the system,” Schwacke says.

That mindset shaped her approach to research. Her early projects focused on the properties these devices need to work well — fast operation, low energy use, and compatibility with semiconductor technology — and on using magnesium ions instead of hydrogen, which can escape into the environment and make devices unstable.

Her current project, the focus of her PhD thesis, centers on understanding how the insertion of magnesium ions into tungsten oxide, a metal oxide whose electrical properties can be precisely tuned, changes its electrical resistance. In these devices, tungsten oxide serves as a channel layer, where resistance controls signal strength, much like synapses regulate signals in the brain.

“I am trying to understand exactly how these devices change the channel conductance,” Schwacke says.

Schwacke’s research was recognized with a MathWorks Fellowship from the School of Engineering in 2023 and 2024. The fellowship supports graduate students who leverage tools like MATLAB or Simulink in their work; Schwacke applied MATLAB for critical data analysis and visualization.

Yildiz describes Schwacke’s research as a novel step toward solving one of AI’s biggest challenges.

“This is electrochemistry for brain-inspired computing,” Yildiz says. “It’s a new context for electrochemistry, but also with an energy implication, because the energy consumption of computing is unsustainably increasing. We have to find new ways of doing computing with much lower energy, and this is one way that can help us move in that direction.”

Like any pioneering work, it comes with challenges, especially in bridging the concepts between electrochemistry and semiconductor physics.

“Our group comes from a solid-state chemistry background, and when we started this work looking into magnesium, no one had used magnesium in these kinds of devices before,” Schwacke says. “So we were looking at the magnesium battery literature for inspiration and different materials and strategies we could use. When I started this, I wasn’t just learning the language and norms for one field — I was trying to learn it for two fields, and also translate between the two.”

She also grapples with a challenge familiar to all scientists: how to make sense of messy data.

“The main challenge is being able to take my data and know that I’m interpreting it in a way that’s correct, and that I understand what it actually means,” Schwacke says.

She overcomes hurdles by collaborating closely with colleagues across fields, including neuroscience and electrical engineering, and sometimes by just making small changes to her experiments and watching what happens next.

Community matters

Schwacke is not just active in the lab. In Kitchen Matters, she and her fellow DMSE grad students set up booths at local events like the Cambridge Science Fair and Steam It Up, an after-school program with hands-on activities for kids.

“We did ‘pHun with Food’ with ‘fun’ spelled with a pH, so we had cabbage juice as a pH indicator,” Schwacke says. “We let the kids test the pH of lemon juice and vinegar and dish soap, and they had a lot of fun mixing the different liquids and seeing all the different colors.”

She has also served as the social chair and treasurer for DMSE’s graduate student group, the Graduate Materials Council. As an undergraduate at Caltech, she led workshops in science and technology for Robogals, a student-run group that encourages young women to pursue careers in science, and assisted students in applying for the school’s Summer Undergraduate Research Fellowships.

For Schwacke, these experiences sharpened her ability to explain science to different audiences, a skill she sees as vital whether she’s presenting at a kids’ fair or at a research conference.

“I always think, where is my audience starting from, and what do I need to explain before I can get into what I’m doing so that it’ll all make sense to them?” she says.

Schwacke sees the ability to communicate as central to building community, which she considers an important part of doing research. “It helps with spreading ideas. It always helps to get a new perspective on what you’re working on,” she says. “I also think it keeps us sane during our PhD.”

Yildiz sees Schwacke’s community involvement as an important part of her resume. “She’s doing all these activities to motivate the broader community to do research, to be interested in science, to pursue science and technology, but that ability will help her also progress in her own research and academic endeavors.”

After her PhD, Schwacke wants to take that ability to communicate with her to academia, where she’d like to inspire the next generation of scientists and engineers. Yildiz has no doubt she’ll thrive.

“I think she’s a perfect fit,” Yildiz says. “She’s brilliant, but brilliance by itself is not enough. She’s persistent, resilient. You really need those on top of that.”

Physicists at MIT have developed a new way to probe inside an atom’s nucleus, using the atom’s own electrons as “messengers” within a molecule.

In a study appearing today in the journal Science, the physicists precisely measured the energy of electrons whizzing around a radium atom that had been paired with a fluoride atom to make a molecule of radium monofluoride. They used the environments within molecules as a sort of microscopic particle collider, which contained the radium atom’s electrons and encouraged them to briefly penetrate the atom’s nucleus.

Typically, experiments to probe the inside of atomic nuclei involve massive, kilometers-long facilities that accelerate beams of electrons to speeds fast enough to collide with and break apart nuclei. The team’s new molecule-based method offers a table-top alternative to directly probe the inside of an atom’s nucleus.

Within molecules of radium monofluoride, the team measured the energies of a radium atom’s electrons as they pinged around inside the molecule. They discerned a slight energy shift and determined that electrons must have briefly penetrated the radium atom’s nucleus and interacted with its contents. As the electrons winged back out, they retained this energy shift, providing a nuclear “message” that could be analyzed to sense the internal structure of the atom’s nucleus.

The team’s method offers a new way to measure the nuclear “magnetic distribution.” In a nucleus, each proton and neutron acts like a small magnet, and they align differently depending on how the nucleus’ protons and neutrons are spread out. The team plans to apply their method to precisely map this property of the radium nucleus for the first time. What they find could help to answer one of the biggest mysteries in cosmology: Why do we see much more matter than antimatter in the universe?

“Our results lay the groundwork for subsequent studies aiming to measure violations of fundamental symmetries at the nuclear level,” says study co-author Ronald Fernando Garcia Ruiz, who is the Thomas A. Franck Associate Professor of Physics at MIT. “This could provide answers to some of the most pressing questions in modern physics.”

The study’s MIT co-authors include Shane Wilkins, Silviu-Marian Udrescu, and Alex Brinson, along with collaborators from multiple institutions including the Collinear Resonance Ionization Spectroscopy Experiment (CRIS) at CERN in Switzerland, where the experiments were performed.

Molecular trap

According to scientists’ best understanding, there must have been almost equal amounts of matter and antimatter when the universe first came into existence. However, the overwhelming majority of what scientists can measure and observe in the universe is made from matter, whose building blocks are the protons and neutrons within atomic nuclei.

This observation is in stark contrast to what our best theory of nature, the Standard Model, predicts, and it is thought that additional sources of fundamental symmetry violation are required to explain the almost complete absence of antimatter in our universe. Such violations could be seen within the nuclei of certain atoms such as radium.

Unlike most atomic nuclei, which are spherical in shape, the radium atom’s nucleus has a more asymmetrical configuration, similar to a pear. Scientists predict that this pear shape could significantly enhance their ability to sense the violation of fundamental symmetries, to the extent that they may be potentially observable.

“The radium nucleus is predicted to be an amplifier of this symmetry breaking, because its nucleus is asymmetric in charge and mass, which is quite unusual,” says Garcia Ruiz, whose group has focused on developing methods to probe radium nuclei for signs of fundamental symmetry violation.

Peering inside the nucleus of a radium atom to investigate fundamental symmetries is an incredibly tricky exercise.

“Radium is naturally radioactive, with a short lifetime and we can currently only produce radium monofluoride molecules in tiny quantities,” says study lead author Shane Wilkins, a former postdoc at MIT. “We therefore need incredibly sensitive techniques to be able measure them.”

The team realized that by placing a radium atom in a molecule, they could contain and amplify the behavior of its electrons.

“When you put this radioactive atom inside of a molecule, the internal electric field that its electrons experience is orders of magnitude larger compared to the fields we can produce and apply in a lab,” explains Silviu-Marian Udrescu PhD ’24, a study co-author. “In a way, the molecule acts like a giant particle collider and gives us a better chance to probe the radium’s nucleus.”

Energy shift

In their new study, the team first paired radium atoms with fluoride atoms to create molecules of radium monofluoride. They found that in this molecule, the radium atom’s electrons were effectively squeezed, increasing the chance for electrons to interact with and briefly penetrate the radium nucleus.

The team then trapped and cooled the molecules and sent them through a system of vacuum chambers, into which they also sent lasers, which interacted with the molecules. In this way the researchers were able to precisely measure the energies of electrons inside each molecule.

When they tallied the energies, they found that the electrons appeared to have a slightly different energy compared to what physicists expect if they did not penetrate the nucleus. Although this energy shift was small — just a millionth of the energy of the laser photon used to excite the molecules — it gave unambiguous evidence of the molecules’ electrons interacting with the protons and neutrons inside the radium nucleus.

“There are many experiments measuring interactions between nuclei and electrons outside the nucleus, and we know what those interactions look like,” Wilkins explains. “When we went to measure these electron energies very precisely, it didn’t quite add up to what we expected assuming they interacted only outside of the nucleus. That told us the difference must be due to electron interactions inside the nucleus.”

“We now have proof that we can sample inside the nucleus,” Garcia Ruiz says. “It’s like being able to measure a battery’s electric field. People can measure its field outside, but to measure inside the battery is far more challenging. And that’s what we can do now.”

Going forward, the team plans to apply the new technique to map the distribution of forces inside the nucleus. Their experiments have so far involved radium nuclei that sit in random orientations inside each molecule at high temperature. Garcia Ruiz and his collaborators would like to be able to cool these molecules and control the orientations of their pear-shaped nuclei such that they can precisely map their contents and hunt for the violation of fundamental symmetries.

“Radium-containing molecules are predicted to be exceptionally sensitive systems in which to search for violations of the fundamental symmetries of nature,” Garcia Ruiz says. “We now have a way to carry out that search.”

Back and better than ever, the Cambridge Science Carnival, an annual free family-friendly science extravaganza, was held on Sunday, Sept. 21, at the Kendall/MIT Open Space.

Founded by the MIT Museum in 2007, and organized with the support of MIT and the City of Cambridge, the 2025 event drew approximately 20,000 attendees and featured more than 140 activities, demonstrations, and installations tied to the topics of science, technology, engineering, arts, and mathematics (STEAM).

Among the carnival’s wide variety of activities was the popular robot petting zoo, an annual showcase involving more than a dozen companies and local robotics clubs, including FIRST Tech Challenge and FIRST Robotics Competition. Participants were invited to engage with a range of different robots, from building with LEGOs and erector sets to piloting underwater robots to learning about the science of automation.

“Every exhibit and every moment of discovery today reinforces why Cambridge remains a global leader in STEAM,” Cambridge Mayor Denise Simmons said in her remarks at the event. “The creativity, ingenuity, and joy on display here today are a powerful reminder that science isn’t just for labs and lecture halls — it’s for everyone.”

Other activities included an appearance from the popular kid-friendly podcast “Tumble Science,” with co-host Marshall Escamilla testing fans’ knowledge of different STEAM topics drawn from “Tumble Science.” Clark University’s smoke-ring air cannons were a particular hit with the under-7-year-old set, while “Cycle To Science” showed off a gravity-defying bicycle wheel that, while spinning, was suspended on one side by a simple piece of string. Attendees also enjoyed live music, food trucks, and activities exploring everything from pipette art to the chemistry of glass. 

At the robot petting zoo, FIRST Robotics volunteer mentor Dominique Regli reflected on the event as someone who was herself first inspired by similar festivals more than a decade earlier. 

“Seeing kids of all ages interact with the robots made me think back to when I was a seventh grader, and how getting to see some of these robots for the first time was truly life-changing for me,” said Regli, who has been involved with FIRST Robotics since 2018 and is now an MIT computer science PhD student and affiliate of the Computer Science and Artificial Intelligence Laboratory (CSAIL). “These types of events are so important to expose students to what's possible.”

Throughout its history, a key aspect of the carnival has been MIT’s close collaboration with the City of Cambridge, which ran several activities. Cambridge Public School teachers led and the Public Works Department hosted a “Trash or Treasure” activity, which helped teach kids about recycling and composting. The carnival is a major contribution to the Institute’s objective of connecting the MIT ecosystem with Cambridge residents and local communities. 

“Cambridge is one of the world’s leading science cities, with more Nobel laureates per capita than any other city on the planet,” says Michael John Gorman, director of the MIT Museum. “The Cambridge Science Carnival is a beloved day in the Cambridge calendar which brings science out of the labs and onto the streets.” 

With a focus on engaging families and kids ranging from kindergarten to the eighth grade, one important outcome this year was to give undergraduate and graduate students the opportunity to showcase their work and hone their skills in clearly communicating science concepts to the public. There were over 50 activities led by MIT students, as well as participants from other local schools such as Boston College and Boston, Clark, Harvard, Northeastern, and Tufts universities.

Typically organized as part of the annual Cambridge Science Festival, this year the Cambridge Science Carnival returned as a standalone event while the larger festival undergoes a strategic transition for its relaunch in 2026. The MIT Museum offered free admission during the carnival and is always free to Cambridge residents, as well as active military, EBT cardholders, members of the Massachusetts Teachers Association, and MIT ID holders.

“For MIT researchers, discovery often happens in a lab or a classroom, but the truth is, the spark of discovery can happen anywhere,” said Alfred Ironside, MIT vice president for communications, in remarks at the event. “That’s really what today is about: feeding curiosity, encouraging questions, and showing that science is not locked away behind closed doors. It’s for everyone.”

Pills are by far the most convenient form of cancer treatment, but most oral cancer drugs quickly dissolve in the stomach, delivering a burst of chemicals into the bloodstream all at once. That can cause side effects. It also may limit the drug’s effectiveness because its concentration in the blood may become too low after the initial burst.

Now, the startup Enzian Pharmaceutics, founded by Aron Blaesi PhD ’14 and former principal research scientist Nannaji Saka ScD ’74, is developing an oral tablet that delivers drugs into the gastric fluid and the blood steadily over time. The company’s tablets use tiny 3D-printed fibers that turn into a gel-like substance when exposed to water. The tablets have been shown to stay in the stomach of animals for up to a day, slowly degrading while releasing the drug in controlled quantities.

The company is currently validating its tablets’ ability to stay in place in a small number of healthy human volunteers. In about a year, it plans to begin testing the technology’s ability to improve the effectiveness and safety of cancer drugs in patients.

“A lot of orally delivered cancer drugs could benefit from this,” says Blaesi, who incorporated the company in 2016. “Right now, soon after someone has taken a cancer drug, its concentration in the blood can be up to 50 times greater than when they are supposed to take the next pill. During the peak, the drug goes into the heart, it goes into the liver, the brain, and it can cause a lot of problems, while at the end of the dosing interval the concentration in the blood may be too low. By taking out that peak and increasing the time the drug is released, we could improve the effectiveness of treatments and mitigate certain side effects.”

In search of innovation

When Blaesi came to MIT, he knew he wanted his mechanical engineering PhD work to form the basis of a company. Early on, as part of the Novartis-MIT Center for Continuous Manufacturing, he worked on manufacturing pills with an injection molding machine that melted and solidified the material, in contrast to the traditional process of compacting powder. He noticed injection molding made the pills far less porous.

“If you put a typical pill into a fluid or into the stomach, the fluid percolates the pores and quickly dissolves it,” Blaesi explains. “That’s not the case when you have an injection molded product. That’s when Dr. Saka, who I met almost daily to discuss my research with, and I started to realize that microstructure is very important.”

The researchers began exploring how different tablet microstructures changed the rate at which drugs are released. For more precision, they moved from injection molding to 3D printing.

Using MIT machine shops, Blaesi built a 3D printer and produced tightly wound microstructures that could carry the drugs. He focused on fibrous structures with space between the fibers, because they would allow gastrointestinal fluid to percolate the pill and dissolve rapidly. He tested the structures in both his Cambridge, Massachusetts, apartment and at MIT’s shared facilities.

Blaesi then experimented with different carrier materials, finding that the higher the molecular weight, the longer it took the pill to dissolve because the material would absorb water and expand before degrading.

“Initially I thought, ‘Oh no, the drug isn’t being dissolved fast enough anymore,’” Blaesi recalls. “Then we thought, ‘Everything has its place.’ This could stay in the stomach for longer because of the expansion. Then it could release the drug over time. We realized this wouldn’t just improve manufacturing, it would improve the product.”

In 2019, Blaesi and Saka published the first paper on their expandable fibrous tablets for prolonged drug delivery. It received a mixed reception.

“Some reviewers said, ‘Research on similar gastroretentive dosage forms has been done for 40 years and no one’s really succeeded,’” Blaesi recalls. “People said, ‘It will never work. Do experiments in animals and then we’ll talk.’”

Blaesi moved back to Switzerland during the Covid-19 pandemic and ran his animal experiments there.

“The reviewers were right: What we had didn’t work,” Blaesi says. “But we adjusted the design and showed we could make the pill stay in the stomach for longer.”

Inside Enzian’s final tablet design, tiny fibers are arranged in a grid. When water flows into the spaces between the fibers, they expand to form a strong gel-like substance that slowly erodes in the stomach, steadily releasing the drug. In animal studies, Enzian’s team showed its technology allowed tablets to remain in the stomach for 12 to 24 hours before being safely excreted.

The team soon found cancer drugs would be a good fit for their technology.

“A lot of cancer drugs are only soluble in acidic solutions, so they can only be absorbed while the drug is in the stomach,” Blaesi explains. “But on an empty stomach, the drug may be in the stomach for just 30 or 40 minutes at present. For a full stomach, it’s a few hours. And because you have a short time to deliver the drug, you need to release a high dose immediately. That shoots up the blood concentration, and if you dose every 12 hours, the concentration is going down during the other 10 hours.”

From the lab to patients

In upcoming human trials, Enzian plans to use its tablets to deliver a drug for prostate cancer that Blaesi says is currently dosed at several hundred milligrams a day. He hopes to get down to about a tenth of that with a better therapeutic effect.

Enzian also believes its technology could improve treatments for blood, skin, and breast cancers.

“This could really be used to improve treatment for a variety of cancers,” Blaesi says. “We believe this is a more efficient and effective way to deliver drugs.”

Maximizing effectiveness and minimizing side effects is also important in clinical trials, where a new drug’s superiority over existing treatments must be shown, and a single adverse event can end its development.

The upcoming move into patients is the culmination of more than a decade of work for Blaesi, who is confident Enzian can deliver on its promise of improving treatments.

“The opportunity is enormous,” Blaesi says. “So many oral cancer drugs have this delivery problem. We still have to do the efficacy and safety studies on patients, but we expect this to be a game changer.”

On Oct. 20 during its annual meeting, the National Academy of Medicine announced the election of 100 new members, including MIT faculty members Dina Katabi and Facundo Batista, along with three additional MIT alumni.

Election to the National Academy of Medicine (NAM) is considered one of the highest honors in the fields of health and medicine, recognizing individuals who have demonstrated outstanding professional achievement and commitment to service.

Facundo Batista is the associate director and scientific director of the Ragon Institute of MGH, MIT and Harvard, as well as the first Phillip T. and Susan M.

If you think of a single atom as a grain of sand, then a wavelength of visible light — which is a thousand times larger than the atom’s width — is comparable to an ocean wave. The light wave can dwarf an atom, missing it entirely as it passes by. This gulf in size has long made it impossible for scientists to see and resolve individual atoms using optical microscopes alone.

Only recently have scientists found ways to break this “diffraction limit,” to see features that are smaller than the wavelength of light. With new techniques known as super-resolution microscopy, scientists can see down to the scale of a single molecule.

And yet, individual atoms have still been too small for optical microscopes — which are much simpler and less expensive than super-resolution techniques — to distinguish, until now.

In an open-access paper appearing today in Nature Communications, MIT scientists present a new computational method that enables optical microscopes to resolve individual atoms and zero in on their exact locations in a crystal structure.

The team’s new “discrete grid imaging technique,” or DIGIT, is a computational imaging approach that scientists can apply to optical data to calculate the most probable location of individual atoms based on a very important clue: the material’s known atomic configuration. As long as scientists have an idea of what a material’s physical atomic layout should be, they can use this layout as a sort of map to determine where specific atoms or features must be located.

“It’s like you know there’s a seating chart,” says lead author Yuqin “Sophia” Duan, a graduate student in MIT’s Department of Electrical Engineering and Computer Science (EECS). “Previous methods could tell you what section an atom is in. But now we can take this seating chart as prior knowledge, and can pinpoint exactly which seat the atom is in.”

With DIGIT, the team can now pinpoint individual atoms with a resolution of 0.178 angstroms. (One angstrom is one-tenth of a nanometer, which is less than half the width of a single atom). The technique enables optical microscopes to localize atomic-scale features in any material that has a known atomic pattern, such as crystalline materials or certain proteins with repeating molecular chains.

The team says the method could help guide the design of quantum devices, which often require placing individual atoms precisely within a crystal. Beyond quantum technologies, DIGIT can also provide new insights into how defects and impurities shape the behavior of advanced materials — from semiconductors to superconductors.

Duan’s co-authors at MIT are Qiushi Gu, Hanfeng Wang, Yong Hu, Kevin Chen, Matthew Trusheim, and EECS Professor Dirk Englund.

Grid support

Scientists can image features smaller than a nanometer, and sometimes as small as a single atom, but not with optical microscopes. In these cases, they use transmission or scanning electron microscopes, which send high-energy beams of electrons into a sample to generate an image based on the pattern in which the electrons scatter. These electron-based methods produce highly detailed, near-atomic-scale images, but they require imaging in a vacuum and at high energies, and only work in ultrathin, synthetic, or solid-state materials. Electron-based imaging methods are too harsh for more delicate living specimens.

In contrast, optical microscopes work at lower energies, in ambient conditions, and are safe to apply to biological samples. But they cannot discern features past the diffraction limit. Essentially, a microscope is unable to see features that are smaller than half the wavelength of visible light (about 200 to 300 nanometers) that a microscope sends in to probe a sample. Atoms, then, have long eluded optical microscopes.

In 2014, however, the Nobel Prize in Chemistry was awarded to developers of a technique to overcome the diffraction limit. Super-resolution microscopy works by shining laser light on a sample at a specific frequency that is known to resonate with a feature of interest, such as a certain molecule. When that molecule resonates, it effectively announces its presence in the material. With this optical manipulation, scientists can visualize features as small as 10 nanometers, on the scale of a single molecule.

Duan and Englund looked to resolve even smaller features by combining super-resolution techniques with statistical analysis and knowledge of materials that has often been overlooked.

“One thing that gets ignored in imaging optical systems is the physical configuration of your system,” Duan says. “For example, if you want to visualize defects in a diamond system, these defects can only be at certain positions, since they have to follow the grid of the atomic diamond structure. In proteins, there are some structures that grow in an organized grid, and their location must be somewhere along that physical grid.”

The researchers suspected that if they had a reasonably accurate map of a material’s atomic structure (imagine the ball-and-stick models of molecules in a chemistry classroom), they might use such maps as a template and try out many different orientations and rotation angles to find the closest match to whatever features are initially visualized using super-resolution microscopy.

“No one has ever done this before, to include the physical constraints or system information into the resolution technique,” Duan says.

Blurriness, collapsed

To test their idea, the researchers worked with a sample of diamond — a crystal whose microstructure is well-understood and resembles an organized grid, or lattice, of repeating carbon atoms. The researchers blindly knocked out some carbon atoms in the lattice and replaced them with silicon atoms using facilities at MIT.nano. Their goal was to identify and determine the precise locations of the errant silicon atoms.

To do so, they first used established techniques of super-resolution microscopy to probe the diamond sample, using lasers set to specific wavelengths at frequencies known to resonate with the silicon atoms but not the carbon atoms. With this technique, researchers produced images that depicted the silicon atoms, but only as a uniform blur.

The team then applied DIGIT to further resolve the picture. Knowing that diamond in general has a grid-like configuration of carbon atoms, the researchers took this configuration as a map, or seating chart of sorts, and assumed that any silicon atoms that took the place of a carbon atom must sit within the grid, which has a known spacing between atoms.

“Because the silicon atoms are substituting carbon atoms in the lattice, that means they must obey some integer multiple of the atomic spacing of the crystal lattice, separating any two silicon atoms,” Englund says. “That prior knowledge makes the localization different than if you add a purely amorphous material.”

The researchers essentially simulated many possibilities of orientations and rotation angles of the diamond lattice, superimposed on the blurry image of atoms that the super-resolution microscopy technique produced.

“The trick is that, in certain materials, atoms aren’t spread out randomly — they sit on a grid inside a crystal,” Duan explains. “We used that prior knowledge to sharpen the microscope’s picture. Once we factored in that ‘atomic grid,’ the blurriness collapsed, and we could pinpoint exact positions.”

In the end, they found the technique could pinpoint the location of individual silicon atoms within the diamond lattice, with a precision of 0.178 angstroms — the sharpest resolution of any optical-based imaging technique. The team has made the DIGIT code available on GitHub for anyone to apply to their optical measurements, provided their sample of interest has a well-understood atomic structure. Then, they hope that scientists will start to see much finer and detailed features and processes using light.

“It’s a big step — it takes optical microscopes into the realm of atomic scale, something people thought only electron microscopes or X-rays could do,” Duan says. “That opens up a whole new way of studying materials and biology.”

The degree to which someone trusts the information depicted in a chart can depend on their assumptions about who made the data visualization, according to a pair of studies by MIT researchers.

For instance, if someone infers that a graph about a controversial topic like gun violence was produced by an organization they feel is in opposition with their beliefs or political views, they may discredit the information or dismiss the visualization all together.

The researchers found that even the clearest visualizations often communicate more than the data they explicitly depict, and can elicit strong judgments from viewers about the social contexts, identities, and characteristics of those who made the chart.

Readers make these assessments about the social context of a visualization primarily from its design features, like the color palette or the way information is arranged, rather than the underlying data. Often, these inferences are unintended by the designers.

Qualitative and quantitative studies revealed that these social inferences aren’t restricted to certain subgroups, nor are they caused by limited data literacy.

The researchers consolidate their findings into a framework that scientists and communicators can use to think critically about how design choices might affect these social assumptions. Ultimately, they hope this work leads to better strategies for scientific communication.

“If you are scrolling through social media and you see a chart, and you immediately dismiss it as something an influencer has produced just to get attention, that shapes your entire experience with the chart before you even dig into the data. We’ve shown in these papers that visualizations do more than just communicate the data they are depicting — they also communicate other social signals,” says Arvind Satyanarayan, an associate professor in the MIT Department of Electrical Engineering and Computer Science (EECS) and member of the Computer Science and Artificial Intelligence Laboratory (CSAIL) and co-senior author of this research.

He is joined on the paper by co-lead authors Amy Rae Fox, a former CSAIL postdoc, and Michelle Morgenstern, a current postdoc in MIT’s anthropology program; and co-senior author Graham M. Jones, professor of anthropology. Two related papers on this research will be presented at the IEEE Visualization Conference.

Charts as social artifacts

During the height of the Covid-19 pandemic, social media was awash in charts from organizations like the World Health Organization and Centers for Disease Control and Prevention, which were designed to convey information about the spread of disease.

The MIT researchers studied how these visualizations were being used to discuss the pandemic. They found that some citizen scientists were using the underlying data to make visualizations of their own, challenging the findings of mainstream science.

“This was an unexpected discovery as, previously, citizen scientists were typically aligned with mainstream scientists. It took us a few years to figure out how to study this phenomenon more deeply,” Satyanarayan says.

Most research into data visualization studies how charts communicate data. Instead, the researchers wanted to explore visualizations from a social and linguistic perspective to assess the information they convey beyond the data.

Linguistic anthropologists have found that, while language allows people to communicate ideas, it also holds social meaning beyond the words people use. For instance, an accent or dialect can indicate that someone is part of a particular community.

By “pointing” to certain social meanings, identities, and characteristics, language serves what is known as a socio-indexical function.

“We wanted to see if things in the visual language of data communication might point to certain institutions, or the kinds of people in those institutions, that carry a meaning that could be unintended by the makers of the visualization,” Jones says.

To do this, the researchers conducted an initial, qualitative study of users on the social media platform Tumblr. During one-on-one interviews, the researchers showed users a variety of real visualizations from online sources, as well as modified visualizations where they removed the textual information, like titles and axes labels.

Stripping out the textual information was particularly important, since it mimics the way people often interact with online visualizations.

“Our engagement with social media is a few quick seconds. People aren’t taking the time to read the title of a chart or look at the data very carefully,” Satyanarayan says.

The interviews revealed that users made detailed inferences about the people or organizations who created the visualizations based on what they called “vibes,” design elements, like colors or the use of certain graphics. These inferences in turn impacted their trust in the data.

For instance, after seeing a chart with the flags of Georgia and Texas and a graph with two lines in red and black, but no text, one user said, “This kind of looks like something a Texas Republican (legislator) would put on Twitter or on their website, or as part of a campaign presentation.”

A quantitative approach

Building on this initial work, the researchers used the same methodology in three quantitative studies involving surveys sent to larger groups of people from a variety of backgrounds.

They found the same phenomenon: People make inferences about the social context of a visualization based on its design, which can lead to misunderstandings about, and mistrust in, the data it depicts.

For instance, users felt some visualizations were so neatly arranged they believed them to be advertisements, and therefore not trustworthy. In another example, one user dismissed a chart by a Pulitzer-prize winning designer because they felt the hand-drawn graphical style indicated it was made by “some female Instagram influencer who is just trying to look for attention.”

“If that is the first reaction someone has to a chart, it is going to massively impact the degree to which they trust it,” Satyanarayan says.

Moreover, when the researchers reintroduced text in the visualizations from which it had been removed, users still made these social inferences.

Typically, in data visualization, the solution to such a problem would be to create clearer charts or educate people about data literacy. But this research points to a completely different kind of data literacy, Jones says.

“It is not erroneous for people to be drawing these inferences. It requires a lot of cultural knowledge about where visualizations come from, how they are made, and how they circulate. Drawing these inferences is a feature, not a bug, of the way we use signs,” he says.

From these results, they created a classification framework to organize the social inferences users made and the design elements that contributed to them. They hope the typology serves as a tool designers can use to develop more effective visualizations, as well as a starting point for additional studies.

Moving forward, the researchers want to continue exploring the role of data visualizations as social artifacts, perhaps by drilling down on each design feature they identified in the typology. They also want to expand the scope of their study to include visualizations in research papers and scientific journals.

“Part of the value of this work is a methodological contribution to render a set of phenomena amenable to experimental study. But this work is also important because it showcases an interdisciplinary cross-pollination that is powerful and unique to MIT,” Jones says.

This work was supported, in part, by MIT METEOR and PFPFEE fellowships, an Amar G. Bose Fellowship, an Alfred P. Sloan Fellowship, and the National Science Foundation.

Coming from a small high school in rural South Dakota that didn’t offer advanced placement (AP) classes, Titus Roesler ’25 didn’t have the easiest start at MIT. But when his efforts to catch up academically to his peers led to a job as a teaching assistant, it changed everything.

Roesler, who graduated last spring with a bachelor’s degree in electrical engineering and is now working on a master’s, has built a reputation for himself as a student-teacher at MIT. Since discovering his affinity for teaching and mentoring, he’s been a teaching assistant for four different classes and designed two seminars from scratch.

Through teaching, Roesler has not only helped other students, but also improved his own grasp of complex subjects. That includes signal processing, which involves manipulating signals, such as radio waves, to make them more useful for applications like wireless communications. He has become fascinated by the topic and hopes to continue working in the field.

Roesler lights up when talking about teaching, but he didn’t always think it was in the cards.

“I don't know that anyone who knew me pre-MIT would believe that I do things like give recitations to crowded rooms, because I think everyone thought, ‘Titus is that quiet kid, he never talked at all.’”

Learning through teaching

Growing up in Marion, South Dakota, a town with a population around 800, Roesler didn’t have MIT on his radar, but he knew he liked math. His high school capstone project involved helping his classmates on the math section of the ACT, and he tutored a few of his classmates. His teacher let him teach trigonometry one day, and he toured local colleges with the plan of becoming a high school math teacher.

But that changed after he self-studied calculus through MIT’s OpenCourseWare offerings and set his sights on the Institute.

Roesler worked overtime during his first year at MIT to catch up with what his peers had learned back in high school. On his first physics exam, he answered only one question correctly — a multiple-choice question he had guessed on. But MIT’s Experimental Study Group (ESG) kept him afloat during his first year, and it quickly led to more opportunities.

When, in the spring of his first year, his multivariable calculus instructor asked him to stay after class one day, Roesler was sure he was in trouble. She actually wanted to see if he could TA for her next year.

“I was flattered because there was still a month left in the class. Plenty of time for me to fail,” Roesler jokes.

He loved the job. During a Friday night office hour session, he stayed for extra hours to help a student whom he saw a lot of himself in — someone who was also from a rural background and had also entered MIT without a strong mathematics background. He went on to become the student’s tutor. The position gave him the opportunity to be the teacher he’d always wanted to have.

As a TA, “I wasn't coming at things from the perspective of ‘Everyone already knows A, B, C’ before I explained. I would always try to start from the ground up and give my perspective on it,” Roesler says.

From his mentorship and teaching work, he received the Undergraduate Teaching Award from the Department of Electrical Engineering and Computer Science and the Outstanding Associate Advisor Award from the Office of the First Year. After joining ESG during his first year, Roesler stayed on as an associate advisor in the learning community for the next three years. His work earned him the Fiekowsky Award for Excellence in Teaching and the Fiekowsky Award for Community Service.

The right blend

Signal processing, the focus of his graduate work, “is where calculus, geometry, linear algebra, probability, statistics, algorithms, and numerical analysis all come into play on practical problems of real-world interest,” Roesler says. “For me, it’s the right blend of theory and application.”

Due to the field’s wide scope, Roesler notices potential applications for signal processing everywhere, and how different fields intersect within the discipline. “Everything comes together in just the right way,” he says.

He is especially interested in signal-processing problems such as source separation, which aims to recover a set of source signals from a set of mixed signals. During his senior year, he spent two semesters on a project where he wrote a Python program to separate harmonies in Bach chorales.

For his master’s degree, following a summer research internship at MIT Lincoln Laboratory, Roesler has stayed at the laboratory, this time venturing into high-frequency radio communications. He’s currently working on a research project that applies the theory of compressed sensing (which states that, under certain conditions, it is possible to reconstruct signals from very few measurements) to communications.

What fascinates Roesler are “something-from-nothing” problems.

“The kind of problems I’m interested in are underdetermined, inverse problems,” he says. For example, imagine trying to reconstruct a full image from only a handful of pixels. While on the surface this seems impossible, researchers have recovered quality images by applying the techniques of compressed sensing.

Running and serving

Roesler has also spent extensive time running, a sport he’s loved since fifth grade. In 2023, he raced a marathon in 2 hours and 46 minutes and went on to run the Boston Marathon in both 2024 and 2025. To prepare, he spent a lot of time reading up on the psychology of running, which he says was the first time he used the scientific method. Now, he just runs for fun and uses it as a way to focus and collect this thoughts.

He has also served on the executive team of the Undergraduate Mathematics Association, as a resident peer mentor at Baker House, and a tutor for two classes. At the PKG Center, he’s been a program lead and counselor for its pre-orientation program.

Roesler still gets excited about seeing the impact of his teaching. At the end of one semester teaching a tutorial, he took his class on a picnic. They surprised him with a card and a bag of goodies. 

Recalling the moment, he says: “I thought, How does it get better? It was wonderful.”

Nervous system functions, from motion to perception to cognition, depend on the active zones of neural circuit connections, or “synapses,” sending out the right amount of their chemical signals at the right times. By tracking how synaptic active zones form and mature in fruit flies, researchers at The Picower Institute for Learning and Memory at MIT have revealed a fundamental model for how neural activity during development builds properly working connections.

Understanding how that happens is important, not only for advancing fundamental knowledge about how nervous systems develop, but also because many disorders such as epilepsy, autism, or intellectual disability can arise from aberrations of synaptic transmission, says senior author Troy Littleton, the Menicon Professor in The Picower Institute and MIT’s Department of Biology. The new findings, funded in part by a 2021 grant from the National Institutes of Health, provide insights into how active zones develop the ability to send neurotransmitters across synapses to their circuit targets. It’s not instant or predestined, the study shows. It can take days to fully mature, and that is regulated by neural activity.

If scientists can fully understand the process, Littleton says, then they can develop molecular strategies to intervene to tweak synaptic transmission when it’s happening too much or too little in disease.

“We’d like to have the levers to push to make synapses stronger or weaker, that’s for sure,” Littleton says. “And so knowing the full range of levers we can tug on to potentially change output would be exciting.”

Littleton Lab research scientist Yuliya Akbergenova led the study published Oct. 14 in the Journal of Neuroscience.

How newborn synapses grow up

In the study, the researchers examined neurons that send the neurotransmitter glutamate across synapses to control muscles in the fly larvae. To study how the active zones in the animals matured, the scientists needed to keep track of their age. That hasn’t been possible before, but Akbergenova overcame the barrier by cleverly engineering the fluorescent protein mMaple, which changes its glow from green to red when zapped with 15 seconds of ultraviolet light, into a component of the glutamate receptors on the receiving side of the synapse. Then, whenever she wanted, she could shine light and all the synapses already formed before that time would glow red, and any new ones that formed subsequently would glow green.

With the ability to track each active zone’s birthday, the authors could then document how active zones developed their ability to increase output over the course of days after birth. The researchers actually watched as synapses were built over many hours by tagging each of eight kinds of proteins that make up an active zone. At first, the active zones couldn’t transmit anything. Then, as some essential early proteins accumulated, they could send out glutamate spontaneously, but not if evoked by electrical stimulation of their host neuron (simulating how that neuron might be signaled naturally in a circuit). Only after several more proteins arrived did active zones possess the mature structure for calcium ions to trigger the fusion of glutamate vesicles to the cell membrane for evoked release across the synapse.

Activity matters

Of course, construction does not go on forever. At some point, the fly larva stops building one synapse and then builds new ones further down the line as the neuronal axon expands to keep up with growing muscles. The researchers wondered whether neural activity had a role in driving that process of finishing up one active zone and moving on to build the next.

To find out, they employed two different interventions to block active zones from being able to release glutamate, thereby preventing synaptic activity. Notably, one of the methods they chose was blocking the action of a protein called Synaptotagmin 1. That’s important because mutations that disrupt the protein in humans are associated with severe intellectual disability and autism. Moreover, the researchers tailored the activity-blocking interventions to just one neuron in each larva because blocking activity in all their neurons would have proved lethal.

In neurons where the researchers blocked activity, they observed two consequences: the neurons stopped building new active zones and instead kept making existing active zones larger and larger. It was as if the neuron could tell the active zone wasn’t releasing glutamate and tried to make it work by giving it more protein material to work with. That effort came at the expense of starting construction on new active zones.

“I think that what it’s trying to do is compensate for the loss of activity,” Littleton says.

Testing indicated that the enlarged active zones the neurons built in hopes of restarting activity were functional (or would have been if the researchers weren’t artificially blocking them). This suggested that the way the neuron sensed that glutamate wasn’t being released was therefore likely to be a feedback signal from the muscle side of the synapse. To test that, the scientists knocked out a glutamate receptor component in the muscle, and when they did, they found that the neurons no longer made their active zones larger.

Littleton says the lab is already looking into the new questions the discoveries raise. In particular: What are the molecular pathways that initiate synapse formation in the first place, and what are the signals that tell an active zone it has finished growing? Finding those answers will bring researchers closer to understanding how to intervene when synaptic active zones aren’t developing properly.

In addition to Littleton and Akbergenova, the paper’s other authors are Jessica Matthias and Sofya Makeyeva.

In addition to the National Institutes of Health, The Freedom Together Foundation provided funding for the study.

When it comes to artificial intelligence, MIT and IBM were there at the beginning: laying foundational work and creating some of the first programs — AI predecessors — and theorizing how machine “intelligence” might come to be.

Today, collaborations like the MIT-IBM Watson AI Lab, which launched eight years ago, are continuing to deliver expertise for the promise of tomorrow’s AI technology. This is critical for industries and the labor force that stand to benefit, particularly in the short term: from $3-4 trillion of forecast global economic benefits and 80 percent productivity gains for knowledge workers and creative tasks, to significant incorporations of generative AI into business processes (80 percent) and software applications (70 percent) in the next three years.

While industry has seen a boom in notable models, chiefly in the past year, academia continues to drive the innovation, contributing most of the highly cited research. At the MIT-IBM Watson AI Lab, success takes the form of 54 patent disclosures, an excess of 128,000 citations with an h-index of 162, and more than 50 industry-driven use cases. Some of the lab’s many achievements include improved stent placement with AI imaging techniques, slashing computational overhead, shrinking models while maintaining performance, and modeling of interatomic potential for silicate chemistry.

“The lab is uniquely positioned to identify the ‘right’ problems to solve, setting us apart from other entities,” says Aude Oliva, lab MIT director and director of strategic industry engagement in the MIT Schwarzman College of Computing. “Further, the experience our students gain from working on these challenges for enterprise AI translates to their competitiveness in the job market and the promotion of a competitive industry.”

“The MIT-IBM Watson AI Lab has had tremendous impact by bringing together a rich set of collaborations between IBM and MIT’s researchers and students,” says Provost Anantha Chandrakasan, who is the lab’s MIT co-chair and the Vannevar Bush Professor of Electrical Engineering and Computer Science. “By supporting cross-cutting research at the intersection of AI and many other disciplines, the lab is advancing foundational work and accelerating the development of transformative solutions for our nation and the world.”

Long-horizon work

As AI continues to garner interest, many organizations struggle to channel the technology into meaningful outcomes. A 2024 Gartner study finds that, “at least 30% of generative AI projects will be abandoned after proof of concept by the end of 2025,” demonstrating ambition and widespread hunger for AI, but a lack of knowledge for how to develop and apply it to create immediate value.

Here, the lab shines, bridging research and deployment. The majority of the lab’s current-year research portfolio is aligned to use and develop new features, capacities, or products for IBM, the lab’s corporate members, or real-world applications. The last of these comprise large language models, AI hardware, and foundation models, including multi-modal, bio-medical, and geo-spatial ones. Inquiry-driven students and interns are invaluable in this pursuit, offering enthusiasm and new perspectives while accumulating domain knowledge to help derive and engineer advancements in the field, as well as opening up new frontiers for exploration with AI as a tool.

Findings from the AAAI 2025 Presidential panel on the Future of AI Research support the need for contributions from academia-industry collaborations like the lab in the AI arena: “Academics have a role to play in providing independent advice and interpretations of these results [from industry] and their consequences. The private sector focuses more on the short term, and universities and society more on a longer-term perspective.”

Bringing these strengths together, along with the push for open sourcing and open science, can spark innovation that neither could achieve alone. History shows that embracing these principles, and sharing code and making research accessible, has long-term benefits for both the sector and society. In line with IBM and MIT’s missions, the lab contributes technologies, findings, governance, and standards to the public sphere through this collaboration, thereby enhancing transparency, accelerating reproducibility, and ensuring trustworthy advances.

The lab was created to merge MIT’s deep research expertise with IBM’s industrial R&D capacity, aiming for breakthroughs in core AI methods and hardware, as well as new applications in areas like health care, chemistry, finance, cybersecurity, and robust planning and decision-making for business.

Bigger isn't always better

Today, large foundation models are giving way to smaller, more task-specific models yielding better performance. Contributions from lab members like Song Han, associate professor in the MIT Department of Electrical Engineering and Computer Science (EECS), and IBM Research’s Chuang Gan help make this possible, through work such as once-for-all and AWQ. Innovations such as these improve efficiency with better architectures, algorithm shrinking, and activation-aware weight quantization, letting models like language processing run on edge devices at faster speeds and reduced latency.

Consequently, foundation, vision, multimodal, and large language models have seen benefits, allowing for the lab research groups of Oliva, MIT EECS Associate Professor Yoon Kim, and IBM Research members Rameswar Panda, Yang Zhang, and Rogerio Feris to build on the work. This includes techniques to imbue models with external knowledge and the development of linear attention transformer methods for higher throughput, compared to other state-of-the-art systems. 

Understanding and reasoning in vision and multimodal systems has also seen a boon. Works like “Task2Sim” and “AdaFuse” demonstrate improved vision model performance if pre-training takes place on synthetic data, and how video action recognition can be boosted by fusing channels from past and current feature maps.

As part of a commitment to leaner AI, the lab teams of Gregory Wornell, the MIT EECS Sumitomo Electric Industries Professor in Engineering, IBM Research’s Chuang Gan, and David Cox, VP for foundational AI at IBM Research and the lab’s IBM director, have shown that model adaptability and data efficiency can go hand in hand. Two approaches, EvoScale and Chain-of-Action-Thought reasoning (COAT), enable language models to make the most of limited data and computation by improving on prior generation attempts through structured iteration, narrowing in on a better response. COAT uses a meta-action framework and reinforcement learning to tackle reasoning-intensive tasks via self-correction, while EvoScale brings a similar philosophy to code generation, evolving high-quality candidate solutions. These techniques help to enable resource-conscious, targeted, real-world deployment.

“The impact of MIT-IBM research on our large language model development efforts cannot be overstated,” says Cox. “We’re seeing that smaller, more specialized models and tools are having an outsized impact, especially when they are combined. Innovations from the MIT-IBM Watson AI Lab help shape these technical directions and influence the strategy we are taking in the market through platforms like watsonx.”

For example, numerous lab projects have contributed features, capabilities, and uses to IBM’s Granite Vision, which provides impressive computer vision designed for document understanding, despite its compact size. This comes at a time when there’s a growing need for extraction, interpretation, and trustworthy summarization of information and data contained in long formats for enterprise purposes.

Other achievements that extend beyond direct research on AI and across disciplines are not only beneficial, but necessary for advancing the technology and lifting up society, concludes the 2025 AAAI panel.

Work from the lab’s Caroline Uhler and Devavrat Shah — both Andrew (1956) and Erna Viterbi Professors in EECS and the Institute for Data, Systems, and Society (IDSS) — along with IBM Research’s Kristjan Greenewald, transcends specializations. They are developing causal discovery methods to uncover how interventions affect outcomes, and identify which ones achieve desired results. The studies include developing a framework that can both elucidate how “treatments” for different sub-populations may play out, like on an ecommerce platform or mobility restrictions on morbidity outcomes. Findings from this body of work could influence the fields of marketing and medicine to education and risk management.

“Advances in AI and other areas of computing are influencing how people formulate and tackle challenges in nearly every discipline. At the MIT-IBM Watson AI Lab, researchers recognize this cross-cutting nature of their work and its impact, interrogating problems from multiple viewpoints and bringing real-world problems from industry, in order to develop novel solutions,” says Dan Huttenlocher, MIT lab co-chair, dean of the MIT Schwarzman College of Computing, and the Henry Ellis Warren (1894) Professor of Electrical Engineering and Computer Science.

A significant piece of what makes this research ecosystem thrive is the steady influx of student talent and their contributions through MIT’s Undergraduate Research Opportunities Program (UROP), MIT EECS 6A Program, and the new MIT-IBM Watson AI Lab Internship Program. Altogether, more than 70 young researchers have not only accelerated their technical skill development, but, through guidance and support by the lab’s mentors, gained knowledge in AI domains to become emerging practitioners themselves. This is why the lab continually seeks to identify promising students at all stages in their exploration of AI’s potential.

“In order to unlock the full economic and societal potential of AI, we need to foster ‘useful and efficient intelligence,’” says Sriram Raghavan, IBM Research VP for AI and IBM chair of the lab. “To translate AI promise into progress, it’s crucial that we continue to focus on innovations to develop efficient, optimized, and fit-for-purpose models that can easily be adapted to specific domains and use cases. Academic-industry collaborations, such as the MIT-IBM Watson AI Lab, help drive the breakthroughs that make this possible.”

Recently, more than 1,000 MIT students stepped into the shoes of global decision-makers by trying out En-ROADS, a simulation tool developed to test climate policies, explore solutions, and envision a cleaner and safer environmental future.

MIT is committed to climate action, and this year’s new student orientation showcased that commitment. For the first time ever, incoming Leaders for Global Operations (LGO), Executive MBA, Sloan Fellow MBA, MBA, and undergraduate students all explored the capabilities of En-ROADS.

“The goal is for MIT to become one of the world’s most prolific, collaborative, and interdisciplinary sources of technological, behavioral, and policy solutions for the global climate challenge over the next decade,” MIT Provost Anantha P. Chandrakasan told an audience of about 300 undergraduates from the Class of 2029. “It is something we need to do urgently, and today is your opportunity to play a role in that bold mission.”

Connecting passion with science for change

In group workshop sessions, students collaborated to create a world in which global warming stays well below 2 degrees Celsius above preindustrial levels — the goal of the 2015 Paris Agreement. Backed by the latest science, the En-ROADS simulator let them explore firsthand how policies like carbon pricing and clean energy investments affect our climate, economy, and health. Over 450 incoming MBA students even role-played as delegates at a global climate summit conference, tasked with negotiating a global agreement to address the harm caused by climate change.

For first-year MBA student Allison Somuk, who played the role of President Xi Jinping of China, the workshop was not only eye-opening about climate, but also altered how she plans to approach her future work and advocacy.

“Before the simulation, I didn’t have data on climate change, so I was surprised to see how close we are to catastrophic temperature increases. What surprised me most was how difficult it was to slow that trajectory. It required significant action and compromise from nearly every sector, not just a few. As someone passionate about improving maternal health care in developing nations, my view of contributing factors has broadened. I now see how maternal health may be affected by a larger system where climate policy decisions directly affect women’s health outcomes.”

MIT Sloan Research Affiliate Andrew Jones, who is also executive director and co-founder of Climate Interactive and co-creator of the En-ROADS tool, presented several sessions during orientation. Looking back on the week, he found the experience personally rewarding.  

“Engaging with hundreds of students, I was inspired by the powerful alignment between their passion for climate action and MIT’s increased commitment to delivering on climate goals. This is a pivotal moment for breakthroughs on our campus.”

Other presenters included Jennifer Graham, MIT Sustainability Initiative senior associate director; Jason Jay, MIT Sustainability Initiative director; Krystal Noiseux, MIT Climate Pathways Project associate director; Bethany Patten, MIT Climate Policy Center executive director; and John Sterman, Jay W. Forrester Professor of Management, professor in the MIT Institute for Data, Systems, and Society, and director of the MIT System Dynamics Group.

Chris Rabe, the MIT Climate Project’s Education Program director, was impressed, but not surprised, by how much students learned so quickly as they worked together to solve the problem with En-ROADS.

“By integrating reflection, emotional dynamics, multi-generational perspectives, group work, and inquiry, the En-ROADS simulation provides an ideal foundation for first-year students to explore the breadth of climate and sustainability opportunities at MIT. In the process, students came to recognize the many levers and multi-solving approaches required to address the complex challenges of climate change.”

Inspiring climate leaders

The En-ROADS workshops were a true team effort, made possible with the help of senior staff at MIT Sloan School of Management and the MBA program office, and members of the MIT Sloan Sustainability Initiative, Climate Pathways Project, Climate Policy Center, the Climate Project, Office of the First Year, and entire undergraduate Orientation team.

“Altogether, over a thousand of the newest members of the MIT community have now had a chance to learn for themselves about the climate crisis,” says Sterman, “and what we can do to create a healthier, safer, more prosperous, and more sustainable world — and how they can get involved to bring that world into being, even as first-year undergrads and MBAs.” 

By the end of the workshops, the students’ spirits were buoyed. They all had successfully found ways to keep global warming to below 2 C.  When asked, “What would you love about being part of this new future you’ve created?,”  a more positive, optimistic word cloud came into view. Answers included:

• breathing cleaner air;
• giving my children a better and safer environment;
• my hometown would not be flooded constantly;
• rich marine life and protection of reefs;
• exciting, new clean industries;
• increased socioeconomic equality; and
• proof that we as a global community can work together to save ourselves. 

First-year MBA student Ruby Eisenbud sums up the sentiment many new MIT students came away with after their workshop.

“Coming to Sloan, one of the questions on my mind was: How can we, as future leaders, make a positive impact related to climate change? While En-ROADS is a simulation, it felt like we experienced, in the smallest way, what it could be like to be a leader navigating the diverging interests of all stakeholders involved in mitigating the impacts of the climate crisis. While the simulation prompted us to face the difficult reality of climate change, it also reinforced my motivation to emphasize climate in my work at Sloan and beyond.”

On any given day, MIT’s famed 825-foot Infinite Corridor serves as a busy, buzzing pedestrian highway, offering campus commuters a quick, if congested, route from point A to B. With the possible exception of MIT Henge twice a year, it doesn’t exactly invite lingering.

Thanks to a recent renovation on the first floor of Building 11, the former location of Student Financial Services, there’s now a compelling reason for students to step off the busy throughfare and pause for conversation or respite.

Dubbed by one onlooker as “the spaceport,” the area has been transformed into an airy, multi-functional hub. Nestled inside is the Undergraduate Advising Center (UAC), which launched in 2023 to provide holistic support for students’ personal and academic growth by providing individualized advising for all four years, offering guidance about and connections to MIT resources, and partnering with faculty and departments to ensure a comprehensive advising experience.

Students can now find another key service conveniently located close by: Career Advising and Professional Development has moved into renovated office suites just down the hall, in Building 7.

“It’s just stunning!” marvels Diep Luu, senior associate dean and director of the UAC. “You can’t help but notice the contrast between the historic architecture and the contemporary design. The space is filled with natural light thanks to the floor-to-ceiling windows, and it makes the environment both energizing and comfortable.”

Designed by Merge Architects, the 5,000 square-foot space opens off the Infinite with several informal public spaces for students and community members. These include a series of soaring, vaulted booths with a variety of tables and seating to support multiple kinds of socialization and/or work, a cozy lounge lined with pi wallpaper (carried out to 10,638 digits after 3.14), and the “social stairs” for informal gatherings and workshops. Beyond that, glass doors lead to the UAC office space, which features open workstations, private advising rooms, and conference rooms with Zoom capability.

“We wanted to incorporate as many different kinds of spaces to accommodate as many different kinds of interactions as we could,” explains Kate Trimble, senior associate dean and chief of staff of the Division of Graduate and Undergraduate Education (GUE), who helped guide the renovation project. “After all, the UAC will support all undergraduate students for their entire four-year MIT journey, through a wide variety of experiences, challenges, and celebrations.”

Homing in on the  “Boardwalk or Park Place of MIT real estate”

The vision for the new district began to percolate in 2022. At the time, GUE (then known as the Office of the Vice Chancellor, or OVC) was focusing on two separate, key priorities: reconfiguring office space in a post-pandemic, flex-work world; and creating a new undergraduate advising center, in accordance with one of the Task Force 2021 recommendations.

A faculty and staff working group gathered information and ideas from offices and programs that had already implemented “flex-space” strategies, such as Human Resources, IS&T, and the MIT Innovation Headquarters. In thinking about an advising center of the size and scope envisioned, Trimble notes, “we quickly zeroed in on the Building 11 space. It’s such a prominent location. Former Vice Chancellor (and current Vice President for Research) Ian A. Waitz referred to it as the “Boardwalk or Park Place of MIT real estate. And if you’re thinking about a center that’s going to serve all undergraduates, you really want it to be convenient and centrally located — and boy, that’s a perfect space.”

As plans were made to relocate Student Financial Services to a new home in Building E17, the renovation team engaged undergraduate students and advising staff in the design process through a series of charrette-style workshops and focus groups. Students shared feedback about spaces on campus where they felt most comfortable, as well as those they disliked. From staff, the team learned which design elements would make the space as functional as possible, allowing for the variety of interactions they typically have with students.

The team selected Merge Architects for the project, Trimble says, because “they understood that we were not looking to build something that was an architectural temple, but rather a functional and fun space that meets the needs of our students and staff. They’ve been creative and responsive partners.” She also credits the MIT Campus Construction group and the Office of Campus Planning for their crucial role in the renovation. “I can’t say enough good things about them. They’ve been superb guides through a long and complicated process.”

A more student-centric Infinite Corridor

Construction wrapped up in late summer, and the UAC held an open house for students on Registration Day, Sept. 3. It buzzed with activity as students admired the space, chatted with UAC staff, took photos, and met the office mascot, Winni, a friendly chocolate Labrador retriever.

“Students have been amazed by the transformation,” says Luu. “We wanted a space that encourages community and collaboration, one that feels alive and dynamic, and the early feedback suggests that’s exactly what’s happening,” Luu explains. “It also gives us a chance to better connect students not only with what the UAC offers, but also with support across the Institute.

“Last year, the UAC offices were behind these two wooden doors in the Infinite Corridor and you had to know that they were there to get to them,” says junior Caleb Mathewos, who has been a UAC orientation leader and captain over the past two years. “The space is very inviting now. I’ve seen people sitting there and working, or just relaxing between classes. I see my friends every now and then, and I’ll stop by and chat with them. Because it’s so much more open, it makes the UAC feel a lot more accessible to students.”

Senior Calvin Macatantan, who’s been involved with the UAC’s First Generation/Low Income Program since his first year and served as an associate advisor and orientation leader, thinks the new space will make it easier for students — especially first years — to find what they need to navigate at MIT. “Before, resources felt scattered across different parts of the Infinite, even though they had similar missions of advising and supporting students. It's nice that there’s a central, welcoming space where those supports connect, and I think that will make a big difference in how students experience MIT.”

The transformation adds significantly to a trend toward creating more student-centric spaces along the Infinite. In the past few years, MIT has added two new study lounges in Building 3, the DEN and the LODGE, and the Department of Materials Science and Engineering built the DMSE Breakerspace in Building 4. This fall, another office suite along the Infinite will be remodeled into a new tutoring hub.

"It’s wonderful to see the UAC space and the whole advising ‘neighborhood,’ if you will, come to fruition,” says Vice Chancellor for Graduate and Undergraduate Education David L. Darmofal. “The need to strengthen undergraduate advising and the opportunity to do so through an Institute advising hub was an outcome of the Task Force 2021 effort, and it’s taken years of thoughtful reflection by many stakeholders to lay the foundation for such a significant sea change in advising. This space is a tangible, visible commitment to putting students first.”

Commercial shipping accounts for 3 percent of all greenhouse gas emissions globally. As the sector sets climate goals and chases a carbon-free future, nuclear power — long used as a source for military vessels — presents an enticing solution. To date, however, there has been no clear, unified public document available to guide design safety for certain components of civilian nuclear ships. A new “Nuclear Ship Safety Handbook” by the MIT Maritime Consortium aims to change that and set the standard for safe maritime nuclear propulsion.

“This handbook is a critical tool in efforts to support the adoption of nuclear in the maritime industry,” explains Themis Sapsis, the William I. Koch Professor of Mechanical Engineering at MIT, director of the MIT Center for Ocean Engineering, and co-director of the MIT Maritime Consortium. “The goal is to provide a strong basis for initial safety on key areas that require nuclear and maritime regulatory research and development in the coming years to prepare for nuclear propulsion in the maritime industry.”

Using research data and standards, combined with operational experiences during civilian maritime nuclear operations, the handbook provides unique insights into potential issues and resolutions in the design efficacy of maritime nuclear operations, a topic of growing importance on the national and international stage. 

“Right now, the nuclear-maritime policies that exist are outdated and often tied only to specific technologies, like pressurized water reactors,” says Jose Izurieta, a graduate student in the Department of Mechanical Engineering (MechE) Naval Construction and Engineering (2N) Program, and one of the handbook authors. “With the recent U.K.-U.S. Technology Prosperity Deal now including civil maritime nuclear applications, I hope the handbook can serve as a foundation for creating a clear, modern regulatory framework for nuclear-powered commercial ships.”

The recent memorandum of understanding signed by the U.S. and U.K calls for the exploration of “novel applications of advanced nuclear energy, including civil maritime applications,” and for the parties to play “a leading role informing the establishment of international standards, potential establishment of a maritime shipping corridor between the Participants’ territories, and strengthening energy resilience for the Participants’ defense facilities.”

“The U.S.-U.K. nuclear shipping corridor offers a great opportunity to collaborate with legislators on establishing the critical framework that will enable the United States to invest on nuclear-powered merchant vessels — an achievement that will reestablish America in the shipbuilding space,” says Fotini Christia, the Ford International Professor of the Social Sciences, director of the Institute for Data, Systems, and Society (IDSS), director of the MIT Sociotechnical Systems Research Center, and co-director of the MIT Maritime Consortium.

“With over 30 nations now building or planning their first reactors, nuclear energy’s global acceptance is unprecedented — and that momentum is key to aligning safety rules across borders for nuclear-powered ships and the respective ports,” says Koroush Shirvan, the Atlantic Richfield Career Development Professor in Energy Studies at MIT and director of the Reactor Technology Course for Utility Executives.

The handbook, which is divided into chapters in areas involving the overlapping nuclear and maritime safety design decisions that will be encountered by engineers, is careful to balance technical and practical guidance with policy considerations.

Commander Christopher MacLean, MIT associate professor of the practice in mechanical engineering, naval construction, and engineering, says the handbook will significantly benefit the entire maritime community, specifically naval architects and marine engineers, by providing standardized guidelines for design and operation specific to nuclear powered commercial vessels.

“This will assist in enhancing safety protocols, improve risk assessments, and ensure consistent compliance with international regulations,” MacLean says. “This will also help foster collaboration amongst engineers and regulators. Overall, this will further strengthen the reliability, sustainability, and public trust in nuclear-powered maritime systems.”

Anthony Valiaveedu, the handbook’s lead author, and co-author Nat Edmonds, are both students in the MIT Master’s Program in Technology and Policy (TPP) within the IDSS. The pair are also co-authors of a paper published in Science Policy Review earlier this year that offered structured advice on the development of nuclear regulatory policies.

“It is important for safety and technology to go hand-in-hand,” Valiaveedu explains. “What we have done is provide a risk-informed process to begin these discussions for engineers and policymakers.”

“Ultimately, I hope this framework can be used to build strong bilateral agreements between nations that will allow nuclear propulsion to thrive,” says fellow co-author Izurieta.

Impact on industry

“Maritime designers needed a source of information to improve their ability to understand and design the reactor primary components, and development of the 'Nuclear Ship Safety Handbook' was a good step to bridge this knowledge gap,” says Christopher J. Wiernicki, American Bureau of Shipping (ABS) chair and CEO. “For this reason, it is an important document for the industry.”

The ABS, which is the American classification society for the maritime industry, develops criteria and provides safety certification for all ocean-going vessels. ABS is among the founding members of the MIT Maritime Consortium. Capital Clean Energy Carriers Corp., HD Korea Shipbuilding and Offshore Engineering, and Delos Navigation Ltd. are also consortium founding members. Innovation members are Foresight-Group, Navios Maritime Partners L.P., Singapore Maritime Institute, and Dorian LPG.

“As we consider a net-zero framework for the shipping industry, nuclear propulsion represents a potential solution. Careful investigation remains the priority, with safety and regulatory standards at the forefront,” says Jerry Kalogiratos, CEO of Capital Clean Energy Carriers Corp. “As first movers, we are exploring all options. This handbook lays the technical foundation for the development of nuclear-powered commercial vessels.”

Sangmin Park, senior vice president at HD Korea Shipbuilding and Offshore Engineering, says “The 'Nuclear Ship Safety Handbook' marks a groundbreaking milestone that bridges shipbuilding excellence and nuclear safety. It drives global collaboration between industry and academia, and paves the way for the safe advancement of the nuclear maritime era.”

MIT has been a leading center of ship research and design for over a century, with work at the Institute today representing significant advancements in fluid mechanics and hydrodynamics, acoustics, offshore mechanics, marine robotics and sensors, and ocean sensing and forecasting. Maritime Consortium projects, including the handbook, reflect national priorities aimed at revitalizing the U.S. shipbuilding and commercial maritime industries.

The MIT Maritime Consortium, which launched in 2024, brings together MIT and maritime industry leaders to explore data-powered strategies to reduce harmful emissions, optimize vessel operations, and support economic priorities.

“One of our most important efforts is the development of technologies, policies, and regulations to make nuclear propulsion for commercial ships a reality,” says Sapsis. “Over the last year, we have put together an interdisciplinary team with faculty and students from across the Institute. One of the outcomes of this effort is this very detailed document providing detailed guidance on how such effort should be implemented safely.”

Handbook contributors come from multiple disciplines and MIT departments, labs, and research centers, including the Center for Ocean Engineering, IDSS, MechE’s Course 2N Program, the MIT Technology and Policy Program, and the Department of Nuclear Science and Engineering.

MIT faculty members and research advisors on the project include Sapsis; Christia; Shirvan; MacLean; Jacopo Buongiorno, the Battelle Energy Alliance Professor in Nuclear Science and Engineering, director, Center for Advanced Nuclear Energy Systems, and director of science and technology for the Nuclear Reactor Laboratory; and Captain Andrew Gillespy, professor of the practice and director of the Naval Construction and Engineering (2N) Program.

“Proving the viability of nuclear propulsion for civilian ships will entail getting the technologies, the economics and the regulations right,” says Buongiorno. “This handbook is a meaningful initial contribution to the development of a sound regulatory framework.”

“We were lucky to have a team of students and knowledgeable professors from so many fields,” says Edmonds. “Before even beginning the outline of the handbook, we did significant archival and history research to understand the existing regulations and overarching story of nuclear ships. Some of the most relevant documents we found were written before 1975, and many of them were stored in the bellows of the NS Savannah.”

The NS Savannah, which was built in the late 1950s as a demonstration project for the potential peacetime uses of nuclear energy, was the first nuclear-powered merchant ship. The Savannah was first launched on July 21, 1959, two years after the first nuclear-powered civilian vessel, the Soviet ice-breaker Lenin, and was retired in 1971.

Historical context for this project is important, because the reactor technologies envisioned for maritime propulsion today are quite different from the traditional pressurized water reactors used by the U.S. Navy. These new reactors are being developed not just in the maritime context, but also to power ports and data centers on land; they all use low-enriched uranium and are passively cooled. For the maritime industry, Sapsis says, “the technology is there, it’s safe, and it’s ready.”

“The Nuclear Ship Safety Handbook” is publicly available on the MIT Maritime Consortium website and from the MIT Libraries. 

The inaugural PITCH.nano competition, hosted by MIT.nano’s hard technology accelerator START.nano, provided a platform for early-stage startups to present their innovations to MIT and Boston’s hard-tech startup ecosystem.

The grand prize winner was Active Surfaces, a startup that is generating renewable energy exactly where it is going to be used through lightweight, flexible solar cells. Active Surfaces says its ultralight, peel-and-stick panels will reimagine how we deploy photovoltaics in the built environment.

Shiv Bhakta MBA ’24, SM ’24, CEO and co-founder, delivered the winning presentation to an audience of entrepreneurs, investors, startup incubators, and industry partners at PITCH.nano on Sept. 30. Active Surfaces received the grand prize of 25,000 nanoBucks — equivalent to $25,000 that can be spent at MIT.nano facilities.

Why has MIT.nano chosen to embrace startup activity as much as we do? asked Vladimir Bulović, MIT.nano faculty director, at the start of PITCH.nano. “We need to make sure that entrepreneurs can be born out of MIT and can take the next technical ideas developed in the lab out into the market, so they can make the next millions of jobs that the world needs.”

The journey of a hard-tech entrepreneur takes at least 10 years and 100 million dollars, explained Bulović. By linking open tool facilities to startup needs, MIT.nano can make those first few years a little bit easier, bringing more startups to the scale-up stage.

“Getting VCs [venture capitalists] to invest in hard tech is challenging,” explained Joyce Wu SM ’00, PhD ’07, START.nano program manager. “Through START.nano, we provide discounted access to MIT.nano’s cleanrooms, characterization tools, and laboratories for startups to build their prototypes and attract investment earlier and with reduced spend. Our goal is to support the translation of fundamental research to real-world solutions in hard tech.”

In addition to discounted access to tools, START.nano helps early-stage companies become part of the MIT and Cambridge innovation network. PITCH.nano, inspired by the MIT 100K Competition, was launched as a new opportunity this year to introduce these hard-tech ventures to the investor and industry community. Twelve startups delivered presentations that were evaluated by a panel of four judges who are, themselves, venture capitalists and startup founders.

“It is amazing to see the quality, diversity, and ingenuity of this inspiring group of startups,” said judge Brendan Smith PhD ’18, CEO of SiTration, a company that was part of the inaugural START.nano cohort. “Together, these founders are demonstrating the power of fundamental hard-tech innovation to solve the world’s greatest challenges, in a way that is both scalable and profitable.”

Startups who presented at PITCH.nano spanned a wide range of focus areas. In the fields of climate, energy, and materials, the audience heard from Addis Energy, Copernic Catalysts, Daqus Energy, VioNano Innovations, Active Surfaces, and Metal Fuels; in life sciences, Acorn Genetics, Advanced Silicon Group, and BioSens8; and in quantum and photonics, Qunett, nOhm Devices, and Brightlight Photonics. The common thread for these companies: They are all using MIT.nano to advance their innovations.

“MIT.nano has been instrumental in compressing our time to market, especially as a company building a novel, physical product,” said Bhakta. “Access to world-class characterization tools — normally out of reach for startups — lets us validate scale-up much faster. The START.nano community accelerates problem-solving, and the nanoBucks award is directly supporting the development of our next prototypes headed to pilot.”

In addition to the grand prize, a 5,000 nanoBucks audience choice award went to Advanced Silicon Group, a startup that is developing a next-generation biosensor to improve testing in pharma and health tech.

Now in its fifth year, START.nano has supported 40 companies spanning a diverse set of market areas — life sciences, clean tech, semiconductors, photonics, quantum, materials, and software. Fourteen START.nano companies have graduated from the program, proving that START.nano is indeed succeeding in its mission to help early-stage ventures advance from prototype to manufacturing. “I believe MIT.nano has a fantastic opportunity here,” said judge Davide Marini, PhD ’03, co-founder and CEO of Inkbit, “to create the leading incubator for hard tech entrepreneurs worldwide.”

START.nano accepts applications on a monthly basis. The program is made possible through the generous support of FEMSA.

Since launching in 2008, the MIT Global Seed Funds (GSF) program has awarded roughly $30 million to more than 1,300 high-impact faculty research projects across the world, spurring consequential collaborations on topics that include swine-fever vaccines, deforestation of the Amazon, the impact of “coral mucus” on the Japanese island of Okinawa, and the creation of an AI-driven STEM-education lab within Nigeria’s oldest university.

Administered by the MIT Center for International Studies (CIS) and open to MIT faculty and principal investigators, GSF boasts a unique funding structure consisting of both a general fund for unrestricted geographical use and more than 20 different specific funds for individual universities, regions, and countries.

GSF projects often tackle critical challenges that require international solutions, culminating in patents, policy changes, and published papers in journals such as Nature and Science. Some faculty-led projects from this year include Professor Hugh Herr’s modular crutches for people with disabilities in Sierra Leone, Research Scientist Paolo Santi’s large-language models to predict energy consumption in grocery stores, and Professor Ernest Fraenkel’s development of mRNA therapies for the neurodegenerative disease amyotrophic lateral sclerosis (ALS).

GSF Assistant Director Justin Leahey, who is managing director of the MIT-Germany and MIT-Switzerland programs, says that GSF has expanded exponentially over the years, including most recently into the Czech Republic, Norway, Slovakia, and — starting in fall 2025 — Hungary. This year there were a grand total of roughly 300 research proposals submitted for consideration, with many of the accepted proposals including the active participation of students at both the graduate and undergraduate level.

Central to GSF’s work is “reciprocal exchange” — the concept of collaborators in and out of MIT sharing their work and exchanging ideas in an egalitarian way, rather than bringing a one-sided approach to different research challenges. Frequent collaborator Raffaella Gozzelino, a neurology researcher and principal investigator at NOVA Medical School in Portugal who works closely with Jacquin Niles, an MIT professor of biological engineering, says that research is more impactful “when specialized knowledge integrates local realities and reveals potential solutions to national challenges,” and views the spirit of reciprocal exchange as something that revolves around “sharing knowledge and co-creating solutions that empower one another and build bridges across borders.”

For Cindy Xie ’24, MCP ’25, her master’s thesis emerged from the first-ever GSF-supported research internship in Cape Verde, where she worked with Niles and Gozzelino to explore the impact of climate change on anemia in the country of 500,000 people, focusing specifically on its largest island of Santiago. Xie says that she was struck by the intertwined intersectional nature of the issues of nutrition, climate, and infection in Santiago, home to the nation’s capital city of Praia. For example, Xie and Gozzelino’s team found that respondents perceived a rise in costs of fresh produce over time, exacerbated by drought and unpredictable agricultural conditions, which in turn impacted existing nutritional deficiencies and increased residents’ susceptibility to mosquito-borne diseases.

“Though this multidisciplinary research lens is challenging in terms of actual project implementation, it was meaningful in that it generated insights and connections across fields that allow our research to be better contextualized within the experiences of the communities that it impacts,” Xie says.

Gozzelino says that it has been meaningful to witness how scientific research can transcend academic boundaries and generate real impact. She says that, by examining the effects of climate change on infectious diseases and nutrition in Cape Verde, the team will be able to build a framework that can directly inform public policy.

“Contributing to a project that underscores the importance of integrating scientific knowledge into decision-making will safeguard vulnerable populations and make them feel included in the society they belong,” Gozzelino says. “This collaboration has revealed the enormous potential of international partnerships to strengthen local research capacity and address global challenges.”

During her time in Cape Verde working with Xie and Gozzelino, Amulya Aluru ’23, MEng ’24 got to meet with 20 local officials and connect with new people in a wide range of roles across the country, helping her “recognize the power of interpersonal relationships and collaboration” in public health research. She says that the structure of the GSF grant gave her the unique experience of having mentors and coworkers in three different countries, spanning Cape Verde, the United States, and Portugal.

Aluru says that this kind of cross-pollination “enabled me to strengthen my research with different perspectives and challenged me to approach my work in a way that I’d never done before, with a more global mindset.”

Xie similarly expresses her deep appreciation for the long-term relationships she has built through the project and the linkages between Santiago and Boston, which itself is home to one of the world’s largest Cape Verdean diasporas. “As a student, this was a valuable experience to inform the approaches to collaboration that I would like to implement in my own future work,” Xie says.

More broadly, Gozzelino sees GSF grants like the Cape Verde one as being not simply a vehicle for financial support, but “a catalyst for turning partnerships into long-term impactful collaborations, demonstrating how global networks can aid the development of human capital.”

GSF’s long history of reaching across departments and borders has led to multiple meaningful academic collaborations that have since come to span continents — and decades. In 2015, Professor Jörn Dunkel — an applied mathematician at MIT — kicked off work on a data-sharing repository for bacterial biofilms with the interdisciplinary German microbiologist Knut Drescher, then a professor of biophysics at Philipps-Universität Marburg in Germany. Dunkel and Drescher have since co-authored more than 15 papers together in publications like Nature Physics and Science Advances alongside their teams of graduate students and postdocs, even with Drescher having moved locations and crossed country lines to Switzerland as a faculty member at the University of Basel’s Biozentrum Center for Molecular Life Sciences.

“Our collaboration often creates great synergy by combining my team’s experiments with the theory from Jörn’s team,” says Drescher. “It is a great joy to see his perspective on the experimental systems we are working on. He is able to really understand and engage with experimental biological data, identifying patterns in seemingly distant biological systems.”

In explaining the CIS initiative’s success, Leahey points to the synergistic, academically eclectic, cross-disciplinary nature of the program. “[GSF] is a research fund that doesn’t ‘fund research’ in the conventional sense,” he says. “It seeds early-stage collaboration and lets people explore.”

The MIT Global Seed Funds applications are now open, with a deadline of Dec. 16.

Alan Robert Whitney ’66, SM ’67, PhD ’74, a longtime research scientist at the MIT Haystack Observatory who also served its associate director and interim director, died on Sept. 28 at age 81.

Whitney was a key contributor to the accomplishments and reputation of Haystack Observatory, having led the development of innovative technologies to advance the powerful radio science technique of very long baseline interferometry (VLBI). He ascended to the rank of MIT principal research scientist, served for many years as associate director of the observatory, and in 2007–08 took the reins as interim director. In 2011, he was awarded an MIT Excellence award.

From an early age, Whitney displayed extraordinary talent. Raised in Wyoming, as a high schooler he won the state science fair in 1962 by building a satellite telemetry receiver, which he designed and built from transistors and other discrete components in a barn on his family’s dairy farm. He enrolled at MIT and completed a five-year master’s degree via a cooperative internship program with Bell Laboratories, subsequently earning his PhD in electrical engineering.

Haystack Director Phil Erickson says, “Alan’s personality and enthusiasm were infectious, and his work represented the best ideals of the Haystack and MIT research enterprise — innovative, curious, and exploring the frontiers of basic and applied science and technology.”

In the late 1960s, as part of his PhD work, he was heavily involved in the pioneering development of VLBI, an extraordinary technique that yielded direct measurements of continental drift and information on distant radio sources at unprecedented angular resolution. A landmark paper led by Whitney demonstrated the presence of apparent superluminal (faster than light) motion of radio sources, which was explained as highly relativistic motion aligned toward the Earth. He spent the rest of his long and productive career at Haystack, pushing forward VLBI technology to ever-greater heights and ever-more impactful scientific capabilities.

“Alan was a technology pillar, a stalwart builder and worldwide ambassador of Haystack, and a leading figure of the VLBI geodetic community who inspired generations of scientists and engineers,” says Pedro Elosegui, leader of the Haystack geodesy group. “He contributed fundamentally to the vision and design of the VLBI Geodetic Observing System, outlining a path to a next-generation VLBI system with unprecedented new capabilities to address emerging space geodesy science needs such as global sea-level rise.”

The early days of VLBI demanded heroic and grueling efforts, traveling the world with exotic devices in hand-carried luggage, mounting and dismounting thousands of magnetic tapes every couple of minutes for hours on end, troubleshooting complex and sensitive instrumentation, and writing highly specialized software for the mainframe computers of the day. Whitney was fully engaged on all these fronts. By the early 1980s, the Mark III recording and correlation systems, whose development was led by Whitney, were established as the state of the art in VLBI technology, and a standard around which the global VLBI community coalesced.

Whitney later led the transition to VLBI disk-based recording. Specialized and robust Mark V systems optimized for shipping logistics and handling were transferred to industry for commercialization, leading once again to widespread global adoption of Haystack-developed VLBI technology. Consistently across all these developments, Whitney identified and exploited the most relevant and practical emerging technologies for the Haystack VLBI mission in hardware, software, and computing infrastructure.

In the latter part of his career, Whitney continued to innovate, pushing the technical boundaries of VLBI. A key advance was the Mark 6 (Mk6) recording system, capable of yet faster recording, higher sensitivity, and more robustness. The Mk6 recorders’ essential capability allowed the creation of the Event Horizon Telescope, which famously yielded the first image of the shadow of a black hole. Mk6 recorders are now used to routinely record data roughly 100,000 times faster than the computer tapes used at the start of his career.

As a senior technical and scientific leader, Whitney provided broad leadership and consultation to Haystack, and worked on a number of projects outside of the VLBI world. He served as interim Haystack director from January 2007 until a permanent director was appointed in September 2008. He also engaged with the development project for the international Murchison Widefield Array (MWA) in Australia, focused on frontier research studying early universe development. Whitney assumed the role of MWA project director from 2008 until groups in Australia took over the construction phase of the project a few years later. Until his full retirement in 2012, Whitney continued to provide invaluable technical insights and support at Haystack, and was a trusted and wise counsel to the Haystack Director’s Office. In 2020, Whitney was a co-recipient of the 2020 Breakthrough Prize in Fundamental Physics awarded to the Event Horizon Telescope Collaboration.

Alan Whitney was a top-notch technologist with a broad perspective that allowed him to guide Haystack to decades of influential leadership in the development and refinement of the VLBI technique. His dedication at MIT to the observatory, its people, and its mission were a source of inspiration to many at Haystack and well beyond. He was widely admired for the clarity of his thought, the sharpness of his intellect, and his genial and friendly nature. His numerous local, national, and global colleagues will feel his absence.
