The distribution of actin inside cells displays spontaneous dynamic behaviors that are similar to those of an excitable medium. The modeling work treats these phenomena with methods including Brownian-dynamics and stochastic-growth simulations, and analytic theory.

The main goals of the modeling are to are to to establish how actin polymerization generates force to "sculpt" the cell membrane in processes such as endocytosis, to pin down the key mechanisms driving migration of cells, to clarify force generation by actomyosin and actin bundles. We are currently expanding our work in mechanobiology to understand how mechanosensitive channels regulate hydration of pollen grains, in collaboration with the Haswell lab at Washington University.
