My primary teaching responsibility is the co-direction and participation in the lecture and laboratory components of the human gross anatomy course taken by the students in the Doctoral Phsyical Therapy Program. I also give the GI lectures in the VIC Human Structure and Function course, and I run a biannual Comparative Neurobiology course for graduate students.
My research focuses on the neurobiology of GI function in health and disease states and uses a variety of experimental approaches including electrophysiology, calcium imaging, immunocytochemistry and molecular biology. Three different questions are under investigation using mice guinea pigs and human tissue.
Gallbladder smooth muscle function. The objectives of our ongoing research are to: (1) elucidate the cellular and ionic mechanisms by which gallbladder smooth muscle contractility is disrupted in gallstone disease; (2) determine the interrelation ship between inflammation and smooth muscle dysfunction in gallstone disease; and (3) explore the utility and mechanisms of hydrophilic bile salts in the protection of gallbladder function by preventing or reversing these disruptions.

Inflammation-induced neuroplasticity in the colon. Discoveries in gut neurobiology over the past two decades have provided us with a solid understanding of the components that make up gut reflex circuits, and how these neurons function under normal physiological conditions. We are now examining what changes occur in various elements of the reflex circuits and the mechanisms responsible for these changes. We are also investigating how these changes influence propulsive motility in the colon.
Mucosal serotonin signaling in the colon. We typically think of serotonin as a neurotransmitter in the brain, but most of the body’s serotonin is actually located in the gastrointestinal tract, and this is where serotonin was initially discovered. Studies conducted in our laboratory and others have demonstrated that various aspects of mucosal serotonin signaling are altered in humans with inflammatory bowel disease or irritable bowel syndrome, as well as animal models of intestinal inflammation. Current studies in our laboratory are directed towards understanding how these changes occur and whether they contribute to altered gut function and sensation. We are also investigating mucosal serotonin receptors as possible targets for the treatment of irritable bowel syndrome.
