Soft matter and complex fluids are ubiquitous in natural and synthetic systems. Our interests lie in the fundamental physics and chemistry that determines the structure and dynamics of these materials. Through studies focused on interfacial phenomena, directed self-assembly, rheology and microfluidics, we advance basic structure-property relationships, materials science, of colloids, liquid crystals, surfactants, polymers and biological materials. Many of these systems have interesting applications as functional materials, for example as sensors, controlled release agents or in photovoltaics and nanomaterials synthesis.
