Epidemiology is a fundamental science of public health, defined as the study of the distribution and determinants of disease and disability in populations. Although epidemiology is historically rooted in the study of the causes of infectious diseases (epidemics), epidemiology now encompasses the study of the full gamut of conditions that impacts the health and well-being of people, families, and their communities.

The MSPH concentration in Epidemiology is an academic degree, geared toward students who want a solid foundation in quantitative research methods and who wish to become members of a public health epidemiologic research team. Students acquire knowledge and skills in study design, data management, analysis and interpretation of study results, with the goal of preventing diseases and promoting well-being. A thesis involving primary or secondary data analysis is required.

An MPH concentration in Epidemiology is also offered. This professional degree is geared toward students who wish to obtain a broad understanding of public health, with an emphasis on epidemiologic principles and quantitative research methods.
