Partial Differential Equations, Nonlinear Analysis

Research Description

I currently work on existence and stability of coherent structures (bound states, solitons, kinks) in Hamiltonian equations and their interaction and coupling with radiation under deterministic and random perturbation. More generally I am interested in hyperbolic and dispersive waves in inhomogeneous and random media and in developing variational and fixed point methods for nonlinear equations to study the existence, stability of solutions and their bifurcations.
