  • Assistant Professor of Epidemiology
Profile Headshot


Christopher Morrison is an Assistant Professor of Epidemiology at the Columbia University Mailman School of Public Health. His research is funded by the U.S. National Institutes of Health and the Centers for Disease Control and Prevention, and seeks to understand how social and physical environmental conditions affect population health, particularly injuries, alcohol use, and alcohol-related harms. His recent work has examined the impacts of ridesharing services (such as Uber and Lyft) on motor vehicle crashes, firearm laws on firearm violence, and retail alcohol availability on alcohol consumption. Dr. Morrison teaches Spatial Epidemiology for masters and doctoral-level students, and serves as Training Coordinator for the Substance Abuse Epidemiology Training Program in the Department of Epidemiology. He previously worked as an Associate Research Scientist at the Prevention Research Center of the Pacific Institute for Research and Evaluation in Berkeley, California, and he completed a postdoctoral fellowship in the Penn Injury Science Center at the University of Pennsylvania. He holds a Ph.D. in epidemiology from Monash University, Australia.
