Research interests:
Similar events characterize disease processes at mucosal sites, such as the intestine and the lungs. Diseases at these sites represent the most common cause of death in humans and other animal species world-wide. The overall aim of my research is to define microbial-host cell interactions in these systems, and how such interactions may affect gastrointestinal and pulmonary physiology, responsiveness, and inflammation, in an attempt to develop novel therapeutic strategies. Particular emphasis is given to research on the pathophysiology of intestinal Giardia infections.
