I am interested in a variety of complex phenomena that arise from competing interactions in systems involving a large number of microscopic degrees of freedom. These include, for example, the pinning of magnetic flux lines in disordered superconductors, the dynamics of interfaces in nonequilibrium growth phenomena, and the formation and recognition of complex patterns in chemical and biological systems. Various aspects of these phenomena are characterized by applying the methods of statistical physics and field theory, and by extending the existing knowledge of disordered and stochastic systems.
