I am a board-certified gastroenterologist who specializes in General GI & inflammatory bowel disease (IBD). I am a tenured professor. I trained at University of Chicago (GI with a post-doc in Immunology) and moved to Northwestern University Hospital (NMH) where I was director of IBD and later division chief of GI. In 2013, I moved to the University of Kentucky where I am now division chief of G.I. and Hepatology with a co-appointment in Microbiology / Immunology. My clinical interest is caring for severe refractory IBD. I have been funded through NIH and VA mechanisms x 30yr & currently study epithelial responses in colitis. The primary interest of our laboratory is the impact of mitochondrial respiration in regulating epithelial cell responses in colitis (RO1-funded). This project led to the development of a novel drug (PCT patent pending), AuPhos, that increases mitochondrial function in the intestine and treats colitis in mice (VA merit-funded).
