Research

Gary’s primary research interests are in computational materials science with emphasis on complex fluids, polymers, self-assembled monolayers, and nanoparticles. Current research activities are focused on nanoparticle suspension rheology and self-assembly, responsive polymer nanocomposites, and interdiffusion of entangled polymers.  Gary's primary CINT activities include modeling nanoparticle assembly, mechanical strength of self-healing polymer films and conjugated polymer nanodots.
