Molecules travel in liquid environments via diffusion. The diffusion of biological molecules is important for function because it determines the time scales for forming encounter complexes.
Diffusion classically described by the Stokes-Einstein equation depends on particle size and solvent viscosity.
We are interested in how diffusive behavior differs due to transient interactions and confinement and how diffusion rates exhibit anomalous behavior, varying as a function of time scale.
We are especially interested in diffusion of proteins and small molecules in concentrated and crowded environments, but we have also studied diffusion in polyelectrolyte systems.
