Research Description

Our lab studies cell division and cell repair in the Xenopus laevis (clawed frog) system. We are particularly interested in how cells coordinate signaling and cytoskeletal dynamics in the cell cortex. During cell division, cells somehow link the position of the mitotic spindle to the cortical signals needed to specify formation of the cytokinetic apparatus such that the cell divides with the proper orientation, a behavior that is essential for the maintenance of stem cell populations. During repair, cells somehow transduce cell damage into a rapid, tightly choreographed series of signaling events and cytoskeletal reorganization, a behavior that is essential for the health and longevity of all cell types, including stem cells.
