Dennis Gaitsgory, mathematician

Israel Gelfand Chair in mathematics

Dennis Gaitsgory is a professor of mathematics at Harvard University, known for his research on the geometric Langlands program.

Dennis Gaitsgory studied at Tel Aviv University under Joseph Bernstein (1990-1996) and received his doctorate in 1997. Prior to his 2021 appointment at Max-Planck-Institute for Mathematics, he was an associate professor at the University of Chicago from 2001–2005 and a professor at Harvard University from 2005-2021.

His work in geometric Langlands culminated in a joint 2002 paper with Edward Frenkel and Kari Vilonen, which established the conjecture for finite fields. In 2004, Dennis Gaitsgory published a separate paper, generalizing the proof to include the field of complex numbers as well.
