Research Abstract:

The goal of my laboratory is to identify and understand how environmental cues regulate the movement of cells about the body during development and disease states. The major disease states we investigate are cancer metastasis and organ fibrosis. To do so we study epithelial morphogenesis (EMT), cell adhesion and migration, and mechanobiology using multidisciplinary approaches through expertise in my lab (molecular cell biology, model organisms, cellular and animal imaging) or long-standing, cooperative, and productive collaborations with investigators at my institution and other institutions (biophysics, engineering, structural chemistry, computational modeling). My laboratory is located in the ICCE Institute (Integration of Communication within the Cancer Environment), of the Siteman Cancer Center at Washington University, where I am the Director. The Institute is dedicated to determining how interactions between tumor cells and their cellular, chemical, and structural microenvironment facilitate tumor progression and metastasis. I also co-direct one of the research programs (basic sciences) at the Siteman Cancer Center of Washington University. I have been fortunate in that @80% of graduate students and over half the postdoctoral fellows I have trained or am currently training have obtained individual, competitive, fellowship support (ACS, AHA, NIH/NCI, HHMI, NSF).
