A Public Health Career in Epidemiology

Whether it’s conducting clinical research, investigating patterns of a disease or collecting complex data, epidemiology is a public health profession that leverages health science information to enhance the well-being of people around the globe.   

By pursuing a Master of Public Health (MPH), you can choose to specialize in epidemiology and address the need for competent public health experts who have the ability to rigorously evaluate scientific information and use it to better society.

What Does an Epidemiologist Do?

Public health research professionals such as epidemiologists analyze health information and collect relevant data to develop awareness about the origin of sickness and disease. Their findings are then applied to a variety of venues, including the regulatory arena, private organizations and public policy.

Epidemiologists perform the following job functions:

  • Plan and direct studies of public health challenges to prevent, treat and anticipate patterns of sickness and disease
  • Collect and analyze data through observations, interviews and surveys, and biological samples to find the causes of sickness and disease
  • Present and communicate their findings to health practitioners, policymakers, private organizations and the public
  • Manage and develop public health programs, monitor their progress and see ways to optimize and innovate research techniques
  • Supervise professional, technical, and medical personnel

How Do I Become an Epidemiologist?

A career in epidemiology typically begins with a bachelor’s degree in biology, medicine or other biological science. Epidemiologists then typically obtain a master’s in public health focusing on biostatistics, behavioral studies, immunology, health services and administration and epidemiological methods.

Many in the field also pursue courses or continuing education in biochemistry or molecular biology so they can specialize in certain numerous applications or variations of epidemiology. This kind of training prepares students to use the tools most commonly associated with the field such as SAS or SPSS statistical software, interviewing techniques and medical processes such as drawing blood.

Where Do Epidemiologists Work?

Due to its diverse nature, epidemiology work environments can vary widely, but no matter the occupational setting, epidemiologists typically work to align evidence with real-world problems and reveal new ways to resolve public health issues around the globe.

Epidemiologists are typically employed at health departments for state and local governments in offices and laboratories. Epidemiologists are hired at hospitals, colleges, universities and federal government agencies, such as the Centers for Disease Control and Prevention (CDC).

Most epidemiologists have a standard schedule and work full time. Occasionally, epidemiologists may have to work long or irregular hours in order to complete fieldwork or tend to duties during public health emergencies.

The median annual wage for epidemiologists was $74,560 in May 2020. In May 2020, the median annual wages for epidemiologists in the top industries in which they worked were as follows:3

  • Scientific research and development services — $99,020
  • Hospitals; state, local and private — $84,420
  • Local government, excluding education and hospitals — $70,470
  • State government, excluding education and hospitals — $68,500
