Department: Vet Microbiology and Immunology More Information Meet a Cornell ResearcherDr. Helene Marquis is an assistant professor of microbiology in the College of Veterinary Medicine. She received a doctorate degree in veterinary medicine from the University of Montreal and received her PhD in veterinary microbiology from Texas A&M University. She then worked as a post-doctoral fellow at the University of Pennsylvania where she studied the pathogenesis of Listeria monocytogenes. In 1997, she assumed a position of assistant professor in the Department of Microbiology at the University of Colorado School of Medicine. In July 2001, she moved to Cornell University.Dr. Marquis continues to study Listeria monocytogenes pathogenesis in her laboratory in the Department of Microbiology and Immunology. Considering that this bacterium is a food borne pathogen that can lead to disease, Dr. Marquis’s research has very important applications to food safety and disease treatment. Her lab is interested in the mechanisms involved in bacterial invasion of the gastro-intestinal tract. She also studies the mechanism controlling the activation and secretion of bacterial proteins that contribute to bacterial escape from double membrane vacuoles. Dr. Marquis accepts undergraduates into her lab and generally looks for them to have a genuine interest in biology and research. She recognizes the fact that most undergrads have not developed a focused interest in any particular field. Therefore she provides undergraduates with the foundational experience necessary to pursue graduate work in the biological sciences. |
