Research Interests

I am interested in problems that come from mathematical physics, especially problems relating to fluid mechanics, kinetic theory and statistical physics. My research tends to focus on the rigorous mathematical aspects of these problems and involves a wide range of tools from dynamical systems, partial differential equations and stochastic analysis. Much of my research involves studying the addition of various types of noise to problems in classical physics, and using tools from stochastic analysis and ergodic theory to study behaviors which would be too complicated to study otherwise. For instance one of my current interests is to use stochastic perturbations in fluid mechanics to prove chaotic and mixing phenomena for passive scalars.
