Dynamics of complex fluids, such as polymeric liquids, emulsions, foams, polymer blends, and liquid crystalline polymers (LCPs). Coupling between the influence of flow on the microstructure of these materials, and hence on the macroscopic material properties. 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.
