Current Focus of Research

The goal of our research group is to extend the basic understanding of soft matter such as colloids, polymers, and nanomaterials to fabricate functional structures with properties designed for advanced applications.  The techniques used in the group include layer-by-layer assembly, microfluidics, optical microscopy, electron microscopy, scanning force microscopy and dissipative quartz crystal microbalance.  Using these techniques we study the interactions of various materials at gas-liquid, liquid-liquid and liquid-solid interfaces.  Intermolecular and capillary forces between materials are used to generate functional thin films and microcapsules for applications in renewable energy, sustained release and encapsulation.
