Jennifer Chayes is one of those rare people whose energy changes a room before she says a word.
She greeted me at UC Berkeley with a huge smile and the kind of enthusiasm you can’t fake. Not just for science, but for life. For discovery. For building things that don’t exist yet.
Jennifer is one of the world’s leading mathematicians and computer scientists. Her research co-founded the field of graphons, fundamentally reshaping how we understand complex networks, phase transitions, and the mathematics of massive systems. It is work that bridges statistical physics and machine learning, laying some of the theoretical foundations for today’s AI revolution.
Yet her true gift may be building institutions. Again and again, she has created places where extraordinary people can do their best work. At Microsoft, she co-founded the Theory Group and later established Microsoft Research New England and Microsoft Research New York. She brought together mathematicians, physicists, economists, computer scientists, and social scientists to tackle problems no single discipline could solve alone.
She brought that same vision to UC Berkeley, where she helped create the College of Computing, Data Science, and Society. Rather than treating data science as an isolated field, she built bridges across the university, weaving computing into fields as diverse as the humanities, climate science, and biomedicine.
Her own path here was anything but conventional. The daughter of Iranian immigrants, she dropped out of high school as a teenager and spent time living on the streets of New York. She eventually found her way back to mathematics in an alternative school held in a church basement, where she taught her classmates because there was no math teacher. Those experiences seem to have given her a rare combination of resilience, empathy, and fearlessness. She is just as comfortable talking about human struggles as she is about complex proofs.
Talking with Jennifer feels less like interviewing a scientist and more like sitting with someone whose mind never stops making connections. Every story leads somewhere unexpected. She moves effortlessly between mathematics, history, technology, and the people behind them. You come away believing that the biggest breakthroughs don’t happen in isolation. They happen when curious people from different worlds come together.
