Life and career

Born in Chișinău (now in Moldova) he grew up in Tajikistan, before studying at Tel Aviv University under Joseph Bernstein (1990–1996). He received his doctorate in 1997 for a thesis entitled "Automorphic Sheaves and Eisenstein Series". He has been awarded a Harvard Junior Fellowship, a Clay Research Fellowship, and the prize of the European Mathematical Society for his work.

His work in geometric Langlands culminated in a joint 2002 paper with Edward Frenkel and Kari Vilonen,^[1] establishing the conjecture for finite fields, and a separate 2004 paper,^[2] generalizing the proof to include the field of complex numbers as well.

Prior to his current appointment at MPIM Bonn, he was a professor of mathematics at Harvard and an associate professor at the University of Chicago from 2001–2005.

Honors and awards

In 2025, he received the Breakthrough Prize in Mathematics.^[3]
