Jason Roy, PhD

Adjunct Faculty

Jason Roy is a Professor of Biostatistics and Chair of the Department of Biostatistics and Epidemiology. He is director of Rutgers University Biostatics and Epidemiology Services (RUBIES) and co-director of Biostatistics, Epidemiology, and Research Design (BERD) core, NJ ACTS. Previously, he was Professor of Biostatistics in the Department of Biostatistics, Epidemiology, and Informatics at the University of Pennsylvania.

Research Interests
Dr. Roy in interested in methodological research in developing flexible Bayesian methods for large, observational studies, especially data from EHR and mobile health. He is particularly interested in causal inference problems, where Bayesian nonparametric methods can be used in conjunction with g-computation. He is also interested in functional clustering methods, which can be very useful for extracting features from intensively collected data (such as from mobile devices). Much of his collaborative research is in pharmacoepidemiology.
