Research Interests
Using rheological techniques to probe the dynamics of polymer liquids is the thrust of Dr. Colby's research program.  Simple notions of scaling are used to construct models for polymer dynamics, allowing for interpretation of the rheology data.  Current research interests include polyelectrolytes, ionomers, liquid crystalline polymers, block copolymers, miscible polymer blends, branched polymers, networks of both charged and uncharged polymers, surfactants, and colloidal suspensions.
