Research Abstract
Cells are highly structured, and this structure is created and maintained using the cytoskeleton in conjunction with molecular motors. My research combines genetic and biochemical manipulations with biophysical techniques ( laser-tweezers, single-particle tracking and analysis, and computer modeling) to study cargo transport in vivo. My primary goal is to understand the extent to which the activity of different molecular motors is coordinated, and the detailed physical changes in motor activity that result in alteration of net cargo transport.
