Eric R. Louderback, PhD is an Instructor in Psychiatry at Harvard Medical School, and a Research & Evaluation Scientist and Open Science Ambassador at the Division on Addiction, Cambridge Health Alliance, a Harvard Medical School teaching hospital. His research is focused on studying addiction within a public health lens, algorithms to predict risky gambling behavior, analysis of data from actual internet gamblers, and responsible gambling program evaluation. Dr. Louderback received his PhD in Sociology with specializations in Medical Sociology and Criminology from the University of Miami in 2018, where he studied the structural causes of neighborhood violence, and social psychological predictors of cybercrime perpetration and victimization.

At the Division, Dr. Louderback is the Section Editor for the Worldwide Addiction Gambling Education Report (The WAGER) and is currently working on several ongoing research projects with Division colleagues, and scholars from U.S. and international universities. These projects include analysis of big data for risk assessment and player safety promotion among subscribers to Entain, a large international gambling operator, and a multi-year evaluation of responsible gambling education programs in U.S. land-based casinos funded by MGM Resorts International. He is also working on a project funded by the Substance Abuse and Mental Health Services Administration (SAMHSA) focused on evaluating an ongoing peer support-based substance abuse treatment program in the Boston area. His research collaborations at the Division utilize the Syndrome Model of Addiction as a guiding framework and he is a strong supporter of transparency and Open Science initiatives. As an Open Science Ambassador, he leads monthly seminars on contemporary scientific and statistical methodologies, best practices for transparency and study replication, and emerging trends in scientific publications.

His research has appeared in journals including PLOS One, Psychology of Addictive Behaviors, Addiction Research & Theory, The British Journal of Criminology, Addictive Behaviors, Journal of Research in Crime and Delinquency, International Gambling Studies, and Journal of Gambling Studies. Dr. Louderback has presented his research studies at national and international conferences to diverse audiences including academic researchers, government policymakers, and the general public. He has served as an expert reviewer in the peer-review process for publications including Addiction Research & Theory, Criminal Justice and Behavior, Criminology, International Journal of Cyber Criminology, Journal of Experimental Criminology and Spatial and Spatio-temporal Epidemiology. Guided by his commitment to educating a new generation of leaders, he has taught quantitative and qualitative research methods at the college level, and he strongly believes that basic scientific knowledge is an integral part of being an informed citizen.
