About

Jeff Cheeger is the Silver Professor of Mathematics at NYU's Courant Institute. His research focuses on the quantitative study of singular sets for geometric nonlinear PDEs, including Einstein manifolds and harmonic maps, and on metric measure spaces with sufficient regularity for first-order calculus, known as PI spaces.
