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[edit]

On August 4, 2008, Shelstad spoke at the Banff International Research Station. The talk was recorded and may be viewed at https://itunes.apple.com/us/podcast/banff-international-research/id307566214.

Awards and honors[edit]

In 2012 she became a fellow of the American Mathematical Society.[1]
