Lasagna Professor of Experimental Therapeutics and Professor of Neurology, Pharmacology and Medicine at the University of Rochester School of Medicine & Dentistry in Rochester, New York, where he currently holds adjunct appointments as Professor of Neurology, Pharmacology & Physiology. He received his MD degree (1971) and postdoctoral training in medicine (1971-73) and neurology (1975-77) at the University of Rochester and in experimental therapeutics at the National Institutes of Health (1973-75).
