Research Summary
Research interests include proteins, polyelectrolytes, ionomers, liquid crystalline polymers, block copolymers, miscible polymer blends, branched polymers, networks, glass-forming liquids, and surfactants and colloidal suspensions. Ion-containing polymers are a poorly understood class of materials that are potentially very important for actuators, sensors, separators between the electrodes of advanced batteries and fuel cell membranes.In the News
