My research is currently focused on the dynamics of complex fluids, such as polymeric liquids, emulsions, foams, polymer blends, and liquid crystalline polymers (LCPs). Much of this is related to the coupling between the influence of flow on the microstructure of these materials, and hence on the macroscopic material properties. Within this broad framework, we are working on: coalescence phenomena; the dynamics of thin liquid films and the control of the stability of such films due to additives such as copolymer surfactants, and nano- or micro-particles; the flow behavior of LCPs, including the formation of disclinations; and the dynamics of entangled polymers. Our tools encompass a spectrum of experimental methods (including several that are unique to our laboratory), as well as theoretical methods based primarily on large-scale computational studies.
