His advisor was Wu-Yi Hsiang. He is now Professor of Mathematics at New York University. Kleiner has written expository papers on the Ricci flow.
Together with John Lott of the University of Michigan, he filled in details of Grigori Perelman"s proof of the Geometrization conjecture (from which the Poincaré conjecture follows) in the years 2003–2006.
Kleiner found a relatively simple proof of Gromov"s theorem on groups of polynomial growth.
