My research program is involved in analyzing genetics of bacteria and requirements of bacteria to interact with appropriate hosts.  The primary research interests of the laboratory are focused towards Campylobacter jejuni, a leading cause of diarrheal disease throughout the world, and Helicobacter pylori, a primary cause of gastritis, gastric ulcers, and gastric cancer.  My laboratory identifies factors required by these bacteria for infection of hosts and analyzes the regulated expression of these factors.  Further detalis regarding my research program can be found at:
