He worked as a teaching assistant and research assistant at Princeton University from 1966–1967, a
National Science Foundation postdoctoral fellow and instructor from 1967–1968, an assistant professor from 1968 to 1969 at the
University of Michigan, and an associate professor from 1969–1971 at
SUNY at Stony Brook. Cheeger was a professor at SUNY, Stony Brook from 1971 to 1985, a leading professor from 1985 to 1990, and a distinguished professor from 1990 until 1992.
He has supervised at least 13 doctoral theses and three postdoctoral fellows. He has served as a member of several
American Mathematical Society committees and National Science Foundation panels.
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.[4]
