Honors and awards

Deift is a fellow of the American Mathematical Society (elected 2012),^[3] a member of the American Academy of Arts and Sciences (elected 2003),^[4] and of the U.S. National Academy of Sciences (elected 2009).^[5][6]

He is a co-winner of the 1998 Pólya Prize,^[1][7] and was named a Guggenheim Fellow in 1999.^[1][8] He gave an invited address at the International Congress of Mathematicians in Berlin in 1998^[1][9][10] and plenary addresses in 2006 at the International Congress of Mathematicians in Madrid and at the International Congress on Mathematical Physics in Rio de Janeiro.^[11] Deift gave the Gibbs Lecture at the Joint Meeting of the American Mathematical Society in 2009.^[12] Along with Michael Aizenman and Giovanni Gallavotti, he won the Henri Poincare Prize in 2018.
