Diana Frost Shelstad (born August 19, 1947) is a mathematician known for her work in automorphic forms. She is a professor at Rutgers–Newark. She earned her doctorate at Yale University in 1974 studying real reductive algebraic groups.



Shelstad has been a key player in the development of the theory of endoscopy which is part of Langlands program. She co-conjectured the fundamental lemma with Robert Langlands in 1984. After over 20 years, this conjecture was solved by Ngô Bảo Châu in 2009, thus opening up a wealth of consequences.

In 1999, Shelstad developed a theory of twisted endoscopy with Robert Kottwitz. In 2008–9 she completed work on tempered endoscopy.

Important talks

On August 4, 2008, Shelstad spoke at the Banff International Research Station. The talk was recorded and may be viewed at

Awards and honors

In 2012 she became a fellow of the American Mathematical Society.
