Epidemiologists conduct research into the patterns and causes of diseases in humans. They work to educate the community and lawmakers on their findings in order to reduce the risks of these problems in the future.
A master’s degree in public health or a related field is generally required to obtain this position. A master's degree typically takes about two-three years to earn after earning a four-year bachelor's degree. For those who conduct research, a doctorate or a medical degree (MD) is likely required. A doctorate or medical degree may take an additional four-five years of work after a bachelor’s degree is earned, depending on the specific program.
Employment of epidemiologists is projected to grow 5 percent from 2019 to 2029, faster than the average for all occupations. Many jobs for these workers are in state and local governments, where they are needed to help respond to emergencies and to provide public health services.
Epidemiologists typically work for the government, universities, or research organizations. They generally work in offices and laboratories, but some may do fieldwork to conduct interviews and collect samples for analyses. Fieldwork may bring epidemiologists into contact with infectious diseases, so they take extensive precautions before interacting with samples or patients.
