Much of Dr. Rosen’s research focuses on the intersection between incarceration and public health. Substantively, his research includes broad assessments of disease prevalence and use of healthcare and mortality among prison-involved populations. He has also conducted several studies examining the use of health services among HIV-infected prisoners and released prisoners. Methodologically, most of Dr. Rosen’s research utilizes the linkage and analysis of large administrative databases to address questions of public health significance for correctional populations and the communities to which they return.
