Professor of Mathematics
Number Theory, Automorphic Forms, Algebraic Geometry

Wei Zhang joined the Math Faculty as Professor in September, 2017.

He received a BS from Peking University in 2004 and a PhD from Columbia University in 2009, both degrees in mathematics. Following a postdoctoral fellowship at Harvard, he was (separately) appointed Benjamin Pierce Fellow at Harvard from 2010-2011. He subsequently joined the mathematics faculty at Columbia University in 2011, and in 2017 MIT mathematics faculty as full professor. Zhang  works in number theory, automorphic forms, and arithmetic geometry. His research program involves fundamental objects such as L-functions, which appear in the Riemann hypothesis and its generalizations, and are central to the Langlands program. He has been developing the theory of relative trace formula to connect L-functions with algebro-geometric objects, notably the discovery of "arithmetic fundamental lemmas". In the function field case, he and Zhiwei Yun have discovered geometric interpretations for the higher derivatives of L-functions. In another direction, Zhang and his collaborators have made significant advances on conjectures subsequent to the Gross--Zagier theorem on elliptic curves, including a proof of the Birch and Swinnerton-Dyer conjecture for approximately 66% of elliptic curves. Zhang received the 2010 SASTRA Ramanujan Prize, the Sloan Research Fellowship in 2013, Morningside Gold Medal of Mathematics at ICCM 2016, and a Simons Fellowship in 2017. In 2018, he gave an invited address at ICM 18 in Rio de Janeiro. He was named a Fellow of the ACM in 2019.
