Sarah Jane Witherspoon is an American mathematician interested in topics in abstract algebra, including Hochschild cohomology and quantum groups.She is a professor of mathematics at Texas A&M University
Witherspoon graduated from Arizona State University in 1988, where she earned the Charles Wexler Mathematics Prize as the best mathematics student at ASU that year. She went on to graduate study in mathematics at the University of Chicago, and completed her Ph.D. in 1994. Her dissertation, supervised by Jonathan Lazare Alperin, was The Representation Ring of the Quantum Double of a Finite Group.
Witherspoon taught at the University of Toronto from 1994 to 1998.After holding visiting assistant professorships atMills College, the University of Wisconsin–Madison,Mount Holyoke College, the University of Massachusetts Amherst, andAmherst College, she joined the Texas A&M faculty in 2004.
She was elected to the 2018 class of fellows of the American Mathematical Society, "for contributions to representation theory and cohomology of Hopf algebras, quantum groups, and related objects, and for service to the profession and mentoring". She was named MSRI Simons Professor for Spring 2020.[1]
