Our primary research focus is the physical behavior and processing characteristics of multiphase (particle-liquid or fluid-liquid) dispersions. We are involved in the development of strategies that exploit or control the colloidal and interfacial chemistry of the system to achieve improved processing behavior and ultimately the enhanced performance of the final materials. We perform fundamental studies of dispersive mixing phenomena for filled polymer composites and morphology development in emulsions. Stability, and the wetting and/or spreading of liquids on dispersed phases are ongoing research interests, and novel experimental approaches to measure these effects are being developed. Transport phenomena occurring in dense two-phase flows are also being modeled. Finally, we have developed several methods that use resonant acoustic fields to perform sharp fine-particle separations with applications in chemical and biochemical processing. Additional studies are dedicated to the development of morphology in dispersions using acoustic processing techniques.
