Personal profile

Research Interests

My research focuses on the role of secreted protein toxins on bacterial pathogenesis. The toxins we study are members of the MARTX family and are produced by Vibrio cholerae, a pathogen important for the diarrheal disease cholera, and Vibrio vulnificus, a pathogen that causes septicemia and necrotizing fasciitis from seafood consumption as well as wound infections. Our group studies the mechanism of action of these toxins using a combination of cell biology, biochemistry, and structural biology. In addition, we investigate the role of these toxins in pathogenesis using animal and tissue culture models with focus on mechanisms of tissue damage and evasion of innate immune clearance.
