Research Interests: Our research goals are to determine (1) how the cytoskeleton controls the organization, shape, and movement of cells and their internal components; (2) how cytoskeletal remodeling is altered by infectious microbes and genetic mutations; and (3) how cytoskeletal functions affect biological aging.  We use a combination of bioinformatic, genetic, biochemical, molecular, cellular, and organismal approaches to study these processes.
