Sergiu Klainerman (born May 13, 1950) is a mathematician known for his contributions to the study of hyperbolic differential equations and general relativity. He is currently the Eugene Higgins Professor of Mathematics at Princeton University, where he has been teaching since 1987.

Biography

He was born in 1950 in Bucharest, Romania, into a Jewish family. After attending the Petru Groza High School,[2] he studied mathematics at the University of Bucharest from 1969 to 1974. For graduate studies he went to New York University, obtaining his Ph.D. in 1978.[3] His thesis, written under the direction of Fritz John and Louis Nirenberg, was titled Global Existence for Nonlinear Wave Equations.[4] From 1978 to 1980 Klainerman was a Miller Research Fellow at the University of California, Berkeley, while from 1980 to 1987 he was a faculty member at New York University's Courant Institute of Mathematical Sciences, rising in rank to Professor in 1986.[3]

Klainerman is a member of the U.S. National Academy of Sciences (elected 2005),[5] a foreign member of the French Academy of Sciences (elected 2002)[6] and a Fellow of the American Academy of Arts and Sciences (elected 1996).[7] He was elected to the 2018 class of fellows of the American Mathematical Society.[8]

He was named a MacArthur Fellow in 1991[9] and Guggenheim Fellow in 1997.[10] Klainerman was awarded the Bôcher Memorial Prize by the American Mathematical Society in 1999 "for his contributions to nonlinear hyperbolic equations".[1] He is currently a co-Editor-in-Chief of Publications Mathématiques de l'IHÉS.[11]
