Robert Kottwitz

Robert Kottwitz (born 1950 in Lynn, Massachusetts) is an American mathematician who works in the Langlands program, including harmonic analysis on p-adic Lie groups, automorphic forms, the general linear groups and Shimura varieties. He studied at the University of Washington and then at Harvard University, where he received his PhD in 1977 with a thesis titled Orbital Integrals on GL3, written under the supervision of Phillip Griffiths and John T. Tate. He was assistant professor and later professor at the University of Washington and moved to the University of Chicago as a professor in 1989, and he was several times a visitor at the Institute for Advanced Study in Princeton. He is a fellow of the American Academy of Arts and Sciences and of the American Mathematical Society, and was an invited speaker at the International Congress of Mathematicians in Berlin in 1998. His writings include a paper with Mark Goresky and Robert MacPherson on equivariant cohomology and Koszul duality, and Foundations of Twisted Endoscopy with Diana Shelstad.
