Complex Fluids and Multiphase Flows

Complex fluids are fluidic mixtures featuring multiple phases and mesoscopic length scales, and include atmospheric aerosols, polymeric solutions and colloidal suspensions. An exciting feature of many complex fluids is their unusual response to external stimulus, such as thermal, chemical, mechanical, electrical or inertial forcing. The intricate dynamics observed in complex fluids, if well understood, can be engineered for numerous applications.

Our group's research interests are in fundamental studies of the dynamics, bifurcations and patterning of complex fluids and multiphase flows, with a specific focus on environmental remediation. Using laboratory experimental techniques and analytic mathematical modeling, we explore such areas as the thermodynamics of electrolyte-containing atmospheric aerosols, fluid dynamics and rheology of polymeric solutions, and electrohydrodynamics of colloidal suspensions.
