Geometry, Topology

Robert Penner's early research was in the fields of low-dimensional topology and dynamical systems. His interests then turned to geometry and he developed the decorated Teichmuller theory of punctured surfaces in a series of papers. He and other researchers have subsequently applied these techniques to various problems in string theory. His current research interests include further development of these interfaces between geometry and physics especially involving algebraic number theory.
