I have 40 years of experience and specialize in the field of pharmacology, with specific knowledge of gastrointestinal drugs, adverse effects and pharmacokinetics. I have published on such topics as gastroprokinetics, irritable bowel syndrome, inflammatory bowel disease, and animal models. I have also been involved with consulting on potential pharmacokinetic problems with preclinical agents. I have performed studies in mice, rats, ferrets, dogs, monkeys and pigs evaluating potential pharmacological activity.
