Bruce Kleiner is a professor of mathematics at the Courant Institute of Mathematical Sciences at New York University. Kleiner received his Ph.D. in mathematics from the University of California, Berkeley in 1990. He received the National Academy of Sciences Award for scientific reviewing of Grigori Perelman’s solution of the Poincaré Conjecture in 2013.
His research interests are in geometric analysis, geometric group theory and geometric topology. These areas involve a mixture of ideas from geometry, analysis, topology and algebra. Current research topics include: geometric evolution equations, such as the Ricci flow and mean curvature flow; quasi-isometric rigidity; quasisymmetric structure of self-similar spaces, such as boundaries of hyperbolic groups; bi-Lipschitz embedding problems; and analysis on singular spaces, such as Carnot groups, and spaces satisfying Poincare inequalities.
