Topologist who contributed to understanding of low dimensional manifolds, especially dimension 3. His discoveries about taut foliations and essential laminations in 3-manifold, and his proof of the famous Property R Conjecture, made him a leader in this precise area. Subsequent discoveries, with collaborators, include work on Seifert fiber spaces, on the Smale Conjecture for hyperbolic 3-manifolds, on the Marden Tameness Conjecture, and the identification of the Week manifold as the closed hyperbolic 3-manifold of minimum volume.
