Bethuel earned his doctorate at Paris-Sud 11 University in 1989, under supervision of Jean-Michel Coron. In 1998 Bethuel was an Invited Speaker of the International Congress of Mathematicians in Berlin.[1] He won the 1999 Fermat Prize, jointly with Frédéric Hélein, for several important contributions to the theory of variational calculus. He also won the 2003 Mergier–Bourdeix Prize [fr] for his fundamental discoveries at the interface between analysis, topology, geometry, and physics.[2]
