Suspension mechanics, colloidal suspensions, fluid mechanics and multiphase flow, rheology.
These are in the properties and dynamics of flowing mixtures, with goal of developing a dynamic materials science. A major focus has been to carry scientific understanding of nonequilibrium microstructure and rheology in sheared suspensions to engineering applications through flow modeling.
