Professional StatementMy laboratory is actively researching Clostridium difficile pathogenesis and we were the first to identify toxin B as the major virulence factor in human intestine. We also identified a novel innate host defense mechanism against microbial toxin and pioneered new therapeutic concepts which we termed “allosteric therapeutics”.
My research has also played a central role in discovering novel glial cell functions in the gut.
