Research

My research interests are in the field of theoretical soft condensed matter physics. With this principal theme, I study problems in statistical mechanics, fluid mechanics, computational physics, biophysics, and Bayesian statistics. My current research focuses on the nonequilibrium statistical mechanics of active and driven systems. An itemized summary of my research is given below.

    1. Phoresis and Stokesian hydrodynamics
    2. Continuum theories of active matter
    3. Stochastic processes
    4. Scientific software
