Leonard L. Howell, Ph.D. (Retired)

Dr. Leonard Howell is an expert in nonhuman primate models of drug addiction. An accomplished scientist, his interests range from basic neurobiology of the central nervous system to medication development for treatment of addiction in humans. He most recently served as Associate Director of Scientific Programs, Chief of the Division of Neuropharmacology and Neurologic Diseases and Director of the Imaging Center, Yerkes National Primate Research Center, and Professor of Psychiatry and Behavioral Sciences and Professor of Pharmacology, Emory University School of Medicine. His research program at Emory over 30 years focused on the neuropharmacology of abused stimulants and included basic neurobiological studies of drug mechanism as well as medications development. The program was translational in its focus and bridged preclinical, nonhuman primate models with therapeutic applications in humans.
