Jeff Cheeger (b. December 1, 1943, Brooklyn, New York City), is a mathematician. Cheeger is professor at the Courant Institute of Mathematical Sciences at New York University in New York City. His main interests are differential geometry and its applications to topology and analysis.

Biography

He graduated from Harvard University with a B.A. in 1964. He graduated from Princeton University with an M.S. in 1966 and with a Ph.D. in 1967.

He worked as a teaching assistant and research assistant at Princeton from 1966-1967. He was an N.S.F. Postdoctoral Fellow and Instructor from 1967-1968. He was an assistant professor from 1968 to 1969 at the University of Michigan. He was an associate professor from 1969-1971 at SUNY at Stony Brook. Cheeger was also a professor at SUNY from 1971 to 1985. He was a leading professor from 1985 to 1992. He was a distingiushed professor at SUNY from 1990 until 1992. Cheeger is a Silver Professor at CIMS, NYU.

Professor Cheeger has also had a number of visiting positions in Brazil (1971), the Institute for Advanced Study (1972, 1977, 1978, 1995), Harvard University (1972), the Institut des Hautes Études Scientifiques (1984-1985) and the Mathematical Sciences Research Institute (1985).

Professor Cheeger has supervised at least 13 doctoral theses and three postdocs. He has served as a member of several AMS committees and NSF panels.

Jeff Cheeger delivered Invited Addresses at the International Congress of Mathematicians in 1974 and in 1986.

Accessed August 11, 2008. Election citation:"Cheeger has discovered many of the deepest results in Riemannian geometry, such as estimates for the spectrum of the Laplace-Beltrami operator, and the identity of the analytic and geometric definitions of torsion, and has led to the solution of problems in topology, graph theory, number theory, and Markov processes."] He received the Fourteenth Oswald Veblen Prize in Geometry from the American Mathematical Society in 2001.
