Jean Loup Waldspurger

Jean-Loup Waldspurger (born 1953) is a French mathematician working on the Langlands program and related areas, who proved Waldspurger's theorem. He played a role in the proof of the fundamental lemma, reducing the conjecture to a version for Lie algebras. This formulation was ultimately proven by Ngô Bảo Châu.

Waldspurger attained his doctorate at École normale supérieure in 1980, under supervision of Marie-France Vignéras. He won the Mergier–Bourdeix Prize of the French Academy of Sciences in 1996. He was awarded the 2009 Clay Research Award for his results in p-adic harmonic analysis.
