Revolve around understanding the interaction of flow and micro-structure in complex fluids, with application to the processing of multifunctional materials, particularly those based on Single-Walled Carbon Nanotubes (SWNTs). Specific problems of interest include: dispersion and liquid crystalline behavior of SWNTs in superacids; spinning of SWNT fibers; coating of transparent, conductive SWNTs films; behavior of individual SWNTs in liquids; entrapment of SWNTs into biocompatible micelles; behavior of SWNTs in confined environments; interaction of flow with flexible and semiflexible molecules; mechanics of blood cells to understand and control hemolysis in blood pumps; modeling complex flows of complex fluids across length scales
