Bethany C. Bray, Ph.D., is Associate Professor in the Department of Medicine at the University of Illinois at Chicago and serves as Associate Director for Scientific Outreach at the Center for Dissemination and Implementation Science, an interdisciplinary research center focused on processes that promote or inhibit the adoption of evidence-based and empirically-supported interventions in real-life settings. Bethany also serves as Director of the Dissemination, Software, and Technology Core of the Center for Complex Data to Knowledge in Drug Abuse and HIV Behavioral Science at Penn State.

Her research focuses on the development and application of advanced latent class modeling techniques to questions about the development of substance use, with special emphasis on its relation to the development of comorbid risk behaviors, such as risky sexual behavior and gambling. Her technical work focuses on flexible approaches to adding predictors, outcomes, moderators, mediators, and inverse propensity score weights to latent class models.

Her work has been funded through the National Institutes of Health, the Alcohol Beverage Medical Research Foundation, and the National Center for Responsible Gaming. She has published articles in a variety of journals, such as Structural Equation Modeling, Methodology, Journal of Studies on Alcohol and Drugs, and Journal of Adolescent Health. Her work has won awards from the National Council on Problem Gambling and the National Center for Responsible Gaming.

Bethany has taught graduate-level courses on research methods, psychometrics, and categorical data analysis. She has taught numerous hands-on workshops on latent class, latent profile, and latent transition analysis, as well as on programming in SAS and R. She has extensive experience presenting technical material to applied scientists. For more information, visit
