Research Interests

My laboratory studies the molecular basis of microbial pathogenesis in Cellular Microbiology where components of the pathogen and host are analyzed to understand the pathogenic process. My research involves the study of bacterial toxins. Several families of bacterial toxins are under investigation: botulinum and tetanus neurotoxins; Certhrax, an ADP-ribosylating exotoxin from Bacillus cereus; and ExoS, a type III cytotoxin of Pseudomonas aeruginosa.
