AI Safety at OpenAI
Professor of Mathematics (on leave) at University of Toronto
Tsimerman is a Fields Medal-winning mathematician whose work helped prove the André–Oort conjecture, a landmark result about patterns among special solutions in arithmetic geometry. He also extended o-minimal methods—tools for controlling complicated geometric behavior—and is now turning to AI safety.
