and then went to Harvard University, where he received his Ph.D. in 1977 under the supervision of Phillip Griffiths and John T. Tate (Orbital Integrals on
He was several times at the Institute for Advanced Study in Princeton, New Jersey (for example, in 1976 and 1977).
Kottwitz works in the Langlands program, including harmonic analysis on p-adic Lie groups and automorphic forms and the general linear groups and Shimura varieties.
