Ronald Kuczenski is Professor of Psychiatry and Neuroscience at the University of California, San Diego School of Medicine. He received his Ph.D. in Biochemistry from Michigan State University in 1970 and did post-doctoral work in the Psychiatry Department at UCSD before he joined the faculty of the Department of Pharmacology at Vanderbilt University in Nashville, Tennessee. He returned to UCSD in 1985 and currently directs a neuropsychopharmacology laboratory in the Department of Psychiatry.
Dr. Kuczenski uses animal models to examine the neurobiological effects associated with acute and long-term exposure to drugs, particularly the psychostimulants such as methylphenidate and methamphetamine. The stimulants produce diverse behavioral effects, ranging from their efficacious actions in the pharmacotherapy of attention deficit hyperactivity disorder to a paranoid psychosis-like syndrome during high-dose stimulant abuse. The long term objectives of this research are to understand the neurochemical mechanisms and processes associated with these behavioral effects.
