Research Interests: 

Research in our laboratory is focused on understanding how aberrant structural organization of the cytoskeleton influences cellular behavior, such as cancer cell invasion and metastasis. The regulation of cellular behavior by structural remodeling of the cytoskeleton exemplifies the paradigm of “structure regulates function” at the cellular level. Our goal is to identify distinct actin cytoskeletal architectures that impact the response of cancer cells to well-known genetic and microenvironmental factors during cancer progression.
