Birgit Speh

Birgit Else Marie Speh (born November 25, 1949 ) is an American mathematician.

Speh received his PhD in 1977 from Bertram Kostant at the Massachusetts Institute of Technology (Some Results on Principal Series of GL (n, R)). She was a post-doctoral student at the University of Chicago. She is a professor at Cornell University . In 1983 she became a research fellow of the Alfred P. Sloan Foundation ( Sloan Research Fellow ).

She deals with representations of semi-simple Lie groups (Speh representations are named after her here) and cohomology of arithmetic groups.

In 2006 she was invited speaker at the International Congress of Mathematicians in Madrid (Representation theory and the cohomology of arithmetic groups). In 2012 she became a Fellow of the American Mathematical Society . She received the Humboldt Research Award . In 2020 Speh Noether will be Lecturer of the American Mathematical Society.
