Anton Kapustin is a Russian-American theoretical physicist and the Earle C. Anthony Professor of Theoretical Physics at the California Institute of Technology and a former member of the Simons Center for Geometry and Physics at Stony Brook University. His main areas of research are quantum field theory in general, with applications to particle physics and condensed matter theory. I am particularly interested in non-perturbative dualities in field theory and string theory, supersymmetry, and Topological Quantum Field Theory.
