Research Interests

Cholera is an ancient waterborne diarrheal disease caused by Vibrio cholerae of serogroup O1 and O139 that continues to affects impoverished populations worldwide. Our research in the biology of V. cholerae covers a broad range of cellular processes relevant to cholera prevention, treatment, pathogenesis and transmission.
