Research

My research has focused on understanding the structure, phase behavior, and self-assembly of complex fluids.  My current work includes studies of ionomers, polymer nanocomposites, and patterned polymer brushes.  I use a variety of techniques, including polymer self-consistent field theory, liquid state theory (PRISM), and molecular dynamics simulations, but my main focus is on the application of classical density functional theory (DFT) to the statistical mechanics of complex fluids, in particular to chain molecules.  Other interests include the modeling of biopolymers near interfaces and/or nanoparticles, and the use of classical DFT to study charged systems.
