Canadian mathematician Jacob Tsimerman, winner of the 2026 Fields Medal, announced on September 8 the launch of the Mathematical AI Safety Institute (MAISI), a research institute dedicated to building rigorous mathematical frameworks for measuring and mitigating the risks of artificial intelligence.
Tsimerman received the Fields Medal in July 2026 for his work on the André-Oort conjecture, becoming the first professor at a Canadian university to win the award. He teaches at the University of Toronto, and his pivot toward AI safety follows a pattern already seen in other fields: applying the rigor of pure mathematics to an area where, until now, most safety guarantees have rested on empirical evaluations rather than formal proofs.
The institute is modeled in part on Princeton's Institute for Advanced Study: it will host mathematicians for semester-long stays dedicated specifically to AI safety problems. According to the announcement, MAISI plans to begin operations in January 2027 with between 10 and 30 mathematicians, scaling up to between 30 and 100 researchers by September 2027. Its advisory panel includes Stanford mathematician Ravi Vakil.
The stated goal is to develop "definitions, measurements, and solution concepts" that would let researchers have reasonable confidence that an AI system won't cause a catastrophe — language aimed at moving AI safety from the realm of policy and general principles into the realm of verifiable proofs.
A detail worth noting for anyone tracking AI safety governance: Tsimerman is taking on the role of Chief Scientist at MAISI at the same time he's joining OpenAI's safety team, also in September 2026. The dual affiliation isn't necessarily a conflict of interest, but it's exactly the kind of link any compliance team should log when assessing the independence of a research institute cited as an external reference.
