Research Interests

My research activities focus on the role of nerves in the gastrointestinal (GI) tract in health and in models of disease. My research spans studies from the brainstem control of GI function in normal animals, to studies of the role of enteric glia in conditions of intestinal inflammation. The GI tract has a dual autonomic innervation and its own, enteric nervous system. The relative roles the different neural components of the gut make to physiological and pathophysiological processes in the intestine is only now being fully understood. My studies seek to explore further both these groups of nerves in the function of the GI tract in health and in inflammatory diseases of the GI tract. Details of these projects can be found at:
