John "Jack" Marshall Lee (born September 2, 1950) is an American mathematician and professor at the University of Washington specializing in differential geometry.
[1] Lee graduated from Princeton University with a bachelor's degree in 1972, then became a systems programmer (at Texas Instruments from 1972 to 1974 and at the Geophysical Fluid Dynamics Laboratory in 1974–1975) and a teacher at Wooster School in Danbury, Connecticut in 1975–1977.
He received his doctorate from Massachusetts Institute of Technology in 1982 under the direction of Richard Melrose with the dissertation Higher asymptotics of the complex Monge-Ampère equation and geometry of CR manifolds.
[2] Lee created a mathematical software package named Ricci for performing tensor calculations in differential geometry.
[2] In 2012, Lee received, jointly with David Jerison, the Stefan Bergman Prize from the American Mathematical Society.
