I have 39 years of experience, and specialize in the field of pharmaceutical sciences with specific knowledge in the areas of pharmacokinetics, pharmaceutics and biopharmaceutics. I have published on such topics as drug disposition in animals and humans, drug-drug interactions and drug absorption. I have testified 25 times on topics such as absorption, drug dissolution, in-vitro in-vivo correlation (IVIVC), metabolism, drug-drug interactions and dosage form assessment. I have advised over 20 graduate students who are primarily in the pharmaceutical industry. I have offered a well-received one-week course in pharmacokinetics to industrial pharmaceutical scientists.
