Education and research activities are structured into four departments: Behavioral and Social Sciences, Biostatistics, Epidemiology, and Health Services, Policy and Practice.

The Department of Behavioral and Social Sciences (BSS)                   
The Department of Behavioral and Social Sciences (BSS) is a multidiscplinary department with over 50 faculty actively engaged in research and teaching to understand the behavioral and social determinants of public health problems and to develop interventions to change behaviors and improve social contexts related to public health. Faculty in BSS conduct collaborative research with a substantive focus on behavioral health issues such as alcohol and other drug abuse;smoking and tobacco use; obesity, nutrition, and physical activity; HIV and sexually transmitted infections; behavioral medicine; and health disparities and culture.  

The Department of Biostatistics                                                               
Biostatistics is a highly dynamic and rapidly expanding scientific area, which is central to the emerging data sciences, and has subject matter grounding in medicine and public health, biology, and the health related social sciences. The Department of Biostatistics is a community of faculty, students, and staff committed to research and education in all aspects of our field. We develop new statistical theory, methods and data analytics; we collaborate in interdisciplinary research across broad areas of subject matter; and we teach students at all levels. 

The Department of Epidemiology                                                                             
The primary mission of the Department of Epidemiology is to provide excellence in teaching and training in the field of epidemiology. The graduate program offers master's and doctoral degrees to prepare students for careers in research or professions in public health which require knowledge of advanced epidemiologic methods. 

The Department of Health Services, Policy and Practice              The mission of the Brown University Department of Health Services, Policy and Practice (HSP&P) in the Public Health Program is to conduct basic and applied research that advances scientific knowledge regarding the determinants of population health, to translate this scientific knowledge into improved public health policy and practice, and to train the next generation of researchers and practitioners.  In pursuit of this mission, HSP&P faculty conducts a broad range of research funded by the NIH and other organizations, and has undergraduate, graduate, medical student and post-doctoral fellowship educational programs.  In addition we have developed relationships with a wide variety of individuals and organizations in Rhode Island state agencies, such as the Department of Health, that allow our faculty and trainees to both provide needed services and be active participants in the policy making process.
