A random walk through the biomolecular landscape;
towards a statistical mechanics of molecular biology

Our laboratory focusses much of its work on the study of biological membranes. Many molecular processes in membranes can usefully be described as a biased random walk. The physics underlying this description is thermal fluctuations in the context of biasing forces derived from biomolecular structures and their environment. Membrane processes with well-developed mathematical descriptions of this type include: ions moving through pathways in membrane proteins, proteins moving laterally in a membrane, opening and closing of ion pathways through membrane proteins, etc. Theoretical analysis and numerical simulation of these processes has yielded useful insights into how membrane molecular assemblies are organized and function. This lecture will review some examples of such theory and computation, and present challenges for future work.
