The S. Allison laboratory is primarily interested in biomolecular transport with particular emphasis in the theory of diffusion, viscosity, and electrophoresis. We have focused on detailed modeling of transport with the objective of learning what electrophoresis, diffusion, and viscosity can tell us about biomolecular charge, conformation, and structure. Over the last few years, we have shown that detailed modeling can accurately predict the electrophoretic mobilities of large classes of peptides and, in specific cases, can be used to address conformational questions as well. Modeling of electrophoresis has been carried out both in free solution and in a gel. Modeling in a gel presents particular challenges and it is in that area where current research is concentrated.
