Research & Publications

Research Summary
My laboratory has two major areas of interest: 1) An NIH-funded program of International Collaborations in Infectious Disease Research, in collaboration with the International Centre for Diarrhoeal Disease Research in Dhaka, Bangladesh, to analyze human mucosal immune responses following natural V. cholerae infection, to analyze gene expression in V. cholerae directly in human samples, to use human immune responses following cholera to identify bacterial genes uniquely expressed during human infection, and to use this information to develop an improved cholera vaccine; 2) Development of live, attenuated strains of V. cholerae as vaccine vectors to deliver heterologous antigens to the common mucosal immune system.
Over 150 original publications on topics in microbiology, immunology, and clinical infectious diseases

  • Cholera strain in Haiti matches bacteria from South Asia

    A team of researchers has determined that the strain of cholera erupting in Haiti matches bacterial samples from South Asia and not those from Latin America. The scientists conclude that the bacteria introduced into Haiti most likely came from an infected human, contaminated food or other item from outside of Latin America.
