Epidemiology and Population Health

Epidemiology is the study of the distribution, determinants, and control of illness and impairment in human populations. It is the cornerstone of population health and informs policy decisions and evidence-based medicine by identifying risk factors for disease and targets for treatment and prevention. The Department of Epidemiology and Population Health (EPH) provides the analytical foundation for research conducted at the Stanford School of Medicine, offering expertise, research, and training on collecting and interpreting the scientific evidence essential to improving human health. 

The scholars within EPH conduct a wide variety of health-related research. Using observational and experimental research methods, our scholars uncover environmental, social, genetic, and behavioral factors to aid in human disease diagnosis, treatment, and prevention. Further, the faculty train physician investigators in techniques of clinical research and are committed to advancing knowledge in epidemiology and population health through educational programs for undergraduate, graduate, and postgraduate students.
