The regulated assembly and organization of specific actin networks drive cell morphology, movement and adhesion. Changes in cell behavior are required to form complex tissue structures during development and must be accompanied by transitions in actin organization. However, the molecular mechanisms governing actin network transitions are poorly understood. The goal of the lab is to understand how actin networks are assembled and organized to regulate cell morphology, movement and adhesion during development. We use a combination of protein biochemistry, cell biology, high-resolution microscopy and developmental biology to study actin dynamics at the molecular, cellular and organismal levels.
