Education:
Georgia Institute of Technology, BS,1989 California Institute of Technology, MS, 1991 California Institute of Technology, PhD, 1996
Areas of Expertise:
Suspension mechanics, colloidal suspensions, fluid mechanics and multiphase flow, rheology
Current Research Interests:

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.
