Robert Clubb*

Research Summary: Bacterial pathogens mount successful infections by displaying virulence factors that enable them to adhere to host tissues, evade the immune response, invade host cells and acquire essential nutrients. I am interested in understanding the molecular mechanisms that underpin virulence factor display and function, and I hope to translate my laboratory’s research findings into practical applications.
