What Epidemiologists Do

Epidemiologists are public health professionals who investigate patterns and causes of disease and injury in humans. They seek to reduce the risk and occurrence of negative health outcomes through research, community education, and health policy.

Work Environment

Epidemiologists work in offices and laboratories, usually at health departments for state and local governments, in hospitals, and at colleges and universities. Some do fieldwork to conduct interviews and collect samples for analyses. Fieldwork may bring epidemiologists into contact with infectious disease, but the risk is minimal because they receive appropriate training and take extensive precautions before interacting with samples or patients.

How to Become an Epidemiologist

Epidemiologists need at least a master’s degree from an accredited college or university. Most epidemiologists have a master’s degree in public health (MPH) or a related field, and some have completed a doctoral degree in epidemiology or medicine.
