Expert Opinions

Description
I am a Board certified internist and PhD clinical pharmacology expert in drug action and effect with over 35 years of experience. 

I have been retained in almost 400 legal cases, for both defendants and plaintiffs, usually in medical malpractice cases in which adverse drug effects or actions are involved. 

I also have extensive expertise in drug litigation and patent disputes. 

In cases where drug prescribing, dosing, adverse effects and drug interactions are in question, I provide standard-of-care expert witness testimony.

I am Board certified in Clinical Pharmacology and in Internal Medicine.

I have been Chairman and Executive Director of the American Board of Clinical Pharmacology, President of the American Society of Clinical Pharmacology and Therapeutics and have been on multiple national committees. 

I teach and practice Clinical Pharmacology and Internal Medicine in an academic and clinical setting.
