We work on problems at the interface of stochastic analysis, statistical mechanics, and scientific computation. Our work is strongly motivated by specific problems in soft condensed matter physics and biophysics. We also work on related problems concerning the analysis and numerical approximation of Stochastic Partial Differential Equations (SPDEs).

Specific research areas include:

  • fluctuating hydrodynamics
  • fluid-structure interaction
  • soft materials and complex fluids (gels and lipid bilayer membranes)
  • biophysics (motor proteins, lipid bilayers, microtubules)
  • electrokinetics in micro/nanofluidic devices

Our work can be classified broadly as:

  • Stochastic Analysis
  • Statistical Physics
  • Numerical Analysis
  • Scientific Computing.
