Suspension flow modeling

Densely packed suspensions of spherical particles are a chaotic dynamical system with fascinating evolution. I focus on non-homogenous flows, particularly flows with sharp gradients in the volume fraction or bidisperse particle sizes or weights. My most recent work focuses on using machine learning to extract more information from simulations or experiments.
