Tim Perutz

Assistant Professor, Department of Mathematics,
University of Texas at Austin

Research interests: low-dimensional topology (especially 4-manifolds) and symplectic geometry.
(In brief: 4 is considered a low number of dimensions, but 5 is not. Symplectic is an adjective describing something fishy.)
