The Department of Mathematics is pleased to announce that Jacob Tsimerman has been named 2025 Fellow of the Royal Society of Canada (RSC). Jacob Tsimerman's work lies at the interface of transcendence theory, analytic number theory, and arithmetic geometry. His accomplishments include proving the André-Oort conjecture, for which he established key results in functional transcendence theory—most notably, the Ax-Schanuel theorem for Hodge structures—and proving the Griffiths conjecture, for which he developed an o-minimal version of the GAGA theorems.
Jacob Tsimerman studied mathematics at the University of Toronto (U of T) and received his doctorate from Princeton University in 2011, under the supervision of Peter Sarnak. He had a postdoctoral position at Harvard University as a Junior Fellow of the Harvard Society of Fellows. In July 2014, he was awarded a Sloan Fellowship and he started his term as assistant professor in the department of Mathematics at the U of T, where he currently holds the position of full professor. Tsimerman has been awarded the 2023 Ostrowski Prize, the 2022 New Horizons in Mathematics Prize, and the 2015 Sastra Ramanujan Prize.
