The Occupational & Environmental Epidemiology (O.E.E.) track provides M.P.H. students with the knowledge, skills, and experiences that will allow them to investigate the human health impacts of exposures to chemical pollutants and non-chemical stressors in people's homes, workplaces, and communities. Our researchers examine exposures including air pollution, metals, pesticides, extreme heat and cold, phthalates and plasticizers, asbestos, noise and more. Health outcomes investigated range from asthma, autism, and birth outcomes in children to cardiovascular disease, metabolic disease, dementia, and mortality in older adults. Our faculty characterize exposures, explore associations between exposure and health, investigate gene-environment interactions and epigenetics, develop novel statistical methods to study multi-pollutant mixtures, and test the effectiveness of public health interventions. O.E.E. is a collaborative program between the Epidemiology and Environmental Health Sciences departments. While all M.P.H. students in the O.E.E track are expected to have an interest in epidemiology and exposures in the environment or workplace, those who would like an emphasis on epidemiological methods may prefer to select Epidemiology as their home department while those who would like more extensive training in exposure science to support epidemiology may consider applying through the Environmental Health Sciences. The MPH degree in O.E.E. is earned in a 60-hour sequence of courses that are typically finished after four terms (two years).
