Biography

Professor Clayton J. Radke's research focuses on combining principles of surface and colloid science with engineering technologies to understand how phase boundaries dictate system behavior. He employs modern spectroscopic tools, molecular theory, simulation, and continuum transport and reaction engineering to provide a quantitative description of interfacial behavior that is important for technology development. Specific areas of interest include protein, polymer, and surfactant adsorption in solution, two-phase enzymatic catalysis, interfacial surfactant transport, wetting and spreading, colloid stability, and the dynamics of stability in thin films. His work also addresses chromatography, multiphase disperse phase flow in porous media, wettability and chemical transport reactions in porous media, electrokinetics, pore-level fluid mechanics, tear films, and contact-lens coating physical design.
