Major Field of Interest
- The assembly and functions of type IV pili in the Gram-positive anaerobic pathogenic bacterium, Clostridium perfringens.
- Identifying the cellular mechanisms responsible for secretion of toxins by C. perfringens.
- The interactions of C. perfringens with the host immune system. Specifically, the molecular mechanisms that allow the bacteria to kill, and avoid being killed by, phagocytic cells of the immune system, macrophages and neutrophils.
