Research

My primary research interest is in stochastic processes derived from randomized billiard dynamical systems.  My current project uses these billiard Markov processes to model gas-surface interactions.  We use them to study applications in chemical engineering such as gas diffusion, non-equilibrium steady state behavior, and stochastic thermodynamics.  This work involves both computer based simulation and traditional theorem proving.  We seek a theory of probabilistic mechanics to compliment the success of statistical mechanics.
