Research

My research interests focus on the application of numerical simulations to complex systems containing a wide range of length scales and time scales. The goal is to model the essential physics of the problem in as simple and fundamental a way as possible. By comparing the predictions of numerical simulations of a mathematical model with experimental measurements, we gain understanding of the underlying physical phenomena in situations where analytic theory is impossible. Recent research, illustrated below, includes: instabilities in a rotating suspension; reactive flows in porous media; inertial migration in duct and pipe flows; and hydrodynamic interactions between confined polymers.
