Robert Ronald Jensen (born 6 April 1949) is an American mathematician, specializing in nonlinear partial differential equations with applications to physics, engineering, game theory, and finance.
[2] He received in 1975 his Ph.D. from Northwestern University with thesis Finite difference approximation to the free boundary of a parabolic variational inequality under the supervision of Avner Friedman.
[3] Jensen was from 1975 to 1977 an assistant professor at the University of California, Los Angeles and from 1977 to 1980 a visiting assistant professor at the University of Wisconsin's Mathematics Research Center.
He was a visiting member of Berkeley's Mathematical Sciences Research Institute in 1992, 2005, and 2013.
[1] In 1998 he was an Invited Speaker at the International Congress of Mathematicians in Berlin.
