I have 25 years of experience, and specialize in the field of gastroenterology with specific knowledge in the areas of ulcerative colitis, Crohn’s disease and irritable bowel syndrome. I have published on such topics as diarrhea, constipation and irritable bowel syndrome. I have testified on bile duct perforation and Crohn’s disease. I have been uniquely positioned at the level of translational medicine between drug discovery, drug development, and clinical medicine. I have served not only as a professor of medicine and researcher, but also experienced biotech and pharmaceutical executive, bridging these two worlds.
