Computational Polymer Physics
This research focuses on fundamental aspects of equilibrium and dynamical behavior in complex polymer liquids. Current research uses molecular dynamics to study phase transitions involving three-dimensionally periodic phases of block copolymer melts and the equilibrium and kinetic behavior of block copolymer surfactants in micellar solutions and in micelle-forming copolymer melts. Work on block copolymer melts will focus on the development of methods to compute free energies of ordered phases as functions of unit cell dimensions, in order to accurately locate phase boundaries for such phases. Work on micelle-forming systems will focus on characterizing a variety of slow dynamical phenomena, and on methods to accurately determine free energies of micelles in solutions of nearly insoluble surfactants.
