Jean, Baron Bourgain (French: [buʁɡɛ̃]; 28 February 1954 – 22 December 2018) was a Belgian mathematician. He was a faculty member at the University of Illinois, Urbana-Champaign and, from 1985 until 1995, professor at Institut des Hautes Études Scientifiques at Bures-sur-Yvette in France, and since 1994 at the Institute for Advanced Study in Princeton, New Jersey until 2018. He was an or for the Annals of Mathematics. From 2012–2014, he was appointed a visiting scholar at UC Berkeley.
Bourgain received his Ph.D. from the Vrije Universiteit Brussel in 1977.
His work is in various areas of mathematical analysis such as the geometry of Banach spaces, harmonic analysis, analytic number theory, combinatorics, ergodic theory, partial differential equations, spectral theory and recently also in group theory. He has been recognised by a number of awards, most notably the Fields Medal in 1994.
