My research interests in theoretical physical chemistry are primarily concerned with the structure, phases and dynamics of complex liquid and biological systems. Although the static and transport properties of simple liquid systems are fairly well understood, much less is known about complex liquid systems of great importance in biochemistry and materials chemistry. The unifying theme of our research is the judicious application of analytic theory, computer simulation and computational chemistry to elucidate the molecular foundations of the structure and macroscopic behavior of complex chemical systems. In addition to previous work on the statistical mechanics of time-dependent properties of equilibrium and steady-state fluids, there are currently several projects of particular interest.
