I am interested in applying statistical mechanics and molecular modeling to study the properties of biological or synthetic macromolecules
Network polymers. I am interested in developing new techniques for characterizing the branching, cyclization, and entanglement patterns of network polymers. There are many well-known synthetic pathways for forming such networks, but relatively little is known about the detailed molecular architecture, or how it varies from one synthesis to another. This research includes applying concepts from graph theory and knot theory to understand and characterize these networks
Transport properties of macromolecules. We have a fascinating new technique for the computation of the diffusivities and the intrinsic viscosities of macromolecules. The technique is powerful enough that we can study macromolecules of arbitrary shape. Computations have been performed on linear chain polymers, (both random coil and wormlike models), star polymers, dendrimers, and proteins.
Glass transition. I have developed a model spin glass, which, unlike other spin glass models, faithfully represents many of the properties of the physical glass transition. Work continues on understanding how this model must be generalized to understand physical glasses
