The conduct of epidemiologic research involves the study of the distribution of disease and/or injury in human populations. The M.S. in Epidemiology degree is designed specifically for students interested in in-depth training and knowledge of the research techniques appropriate to conducting epidemiologic studies in a particular concentration of health research. Master's-level epidemiologists may work in applied settings conducting disease surveillance and outbreak investigations or in research settings developing and evaluating research hypotheses generated to understand the effects of biological, environmental, social, and behavioral factors on human health. Since Epidemiology is the principal science underlying disease prevention and control programs, this training is also a basic component for other degree and training programs in public health and preventative medicine.
