Cytoskeleton and Cell Adhesion
Our lab is interested in on how cells organize an actin cytoskeleton. Current projects focus on how actin filaments are assembled at cell-cell junctions, how actin filaments depolymerize, and how signals trigger actin nucleation. We use a combination of biochemical, biophysical, and cell biological techniques to address these questions which are fundamental for understanding cell shape, cell motility, and morphogenesis.
