Dr. Austin Zamarripa obtained his PhD in Neuroscience from the University of Mississippi Medical Center. During his graduate training, Dr. Zamarripa’s research focused on the development of safer opioid analgesics using preclinical models to determine improved therapeutic outcomes (i.e., increased pain relief) with reduced abuse liability. Currently, Dr. Zamarripa is completing his postdoctoral fellowship under the guidance of Dr. Ryan Vandrey and Dr. Tory Spindle studying the factors (e.g., route of administration, dose, sex) that impact the pharmacokinetic and pharmacodynamic effects of cannabis using controlled clinical laboratory methods. Current research projects seek to characterize the drug-drug interactive effects of cannabis, including the cognitive, psychomotor, and driving-related impairment, when combined with commonly used substances (e.g., alcohol, nicotine).
