Research Description

Our research is currently focused on the fluid dynamics and rheology of complex fluids; and the role of flow and material additives in determining microstuctural configuration and material properties; especially multiphase polymeric materials; nanoparticle and copolymer effects; liquid crystalline polymers, and the role of branching in polymer rheology

Research Groups

Biography

I taught from 1970-1989 in the chemical engineering department at Caltech. I have been at UCSB since 1989. I have courtesy appointments in both Materials and ME.
