I have 37 years of experience and specialize in the field of basic gastroenterology with specific knowledge in the areas of gastrointestinal (GI) pharmacology, GI motility and abdominal pain. I have published on such topics as gut pharmacology, neurogastroenterology, functional gastrointestinal disorders and enteric neuropathy. I have testified on ischemic colitis as a side effect of a 5HT3 blocker.
