What is an Epidemiologist?
Epidemiologists are extensively trained scientific experts who specialize in studying the patterns and causes of illnesses and injuries. Their work is focused on improving overall public health by better understanding how we can reduce the rates of negative health outcomes. That could mean everything from stopping the spread of contagious illnesses to improving treatments for cancer patients.
Epidemiologist: Job Description
What Does an Epidemiologist Do?
Epidemiologists collect and analyze large amounts of data to improve our understanding of a variety of health issues. For example, they may study demographic data to identify most at-risk groups for specific conditions or research trends among patient populations to help improve treatment and screening methods. Epidemiologists can specialize in a number of different fields—like infectious diseases, mental health, maternal and child wellness, or even veterinary epidemiology.
Some of the day-to-day responsibilities of epidemiologists include:
- Planning and coordinating large-scale studies of public health problems
- Collecting and analyzing data to determine the causes of diseases or other health issues
- Communicating important information to policymakers and the general public
- Supervising and coordinating technical, research, or clerical employees
- Writing grant proposals to secure funding for ongoing research
The best epidemiologists are usually people who take naturally to math and statistics, as you’ll need to work with large sets of data to draw meaningful conclusions about how to improve public health. In addition, since epidemiologists frequently lead a team of other public health professionals, leadership and organizational skills are also important. Finally, communication skills are a major plus for a career as an epidemiologist, as you’ll need to make complex topics easy to understand when sharing information with policymakers or the community at large.
Where Do Epidemiologists Work?
Because epidemiologists can specialize in so many different areas, their work environments vary considerably. As a result, jobs for epidemiologists are split relatively evenly between the public and private sectors. Some epidemiologists work primarily in offices and labs, while others spend considerable amounts of time in the field conducting research or investigating health incidents. Most epidemiologists work fairly standard 40-hour weeks, though irregular hours may occasionally be required, particularly during public health emergencies.
Epidemiologist Schooling & Certification
How Long Does It Take to Become an Epidemiologist?
What Degree Do You Need to Be an Epidemiologist?
Becoming an epidemiologist requires several years of specialized training and usually multiple college degrees, though all epidemiologists begin their career by earning at least a bachelor’s degree. While traditional bachelor’s degree programs require a full four years in school, some accelerated degree programs can be completed in just two and a half years. Some colleges offer bachelor’s degree programs focused specifically on public health, though studying public health as an undergrad is not necessarily the only path to a career as an epidemiologist. Other healthcare programs or even degrees in science, math, or statistics can also prepare you for a career as an epidemiologist.
The top epidemiologist jobs will usually require at least one postgraduate degree, and many epidemiologists earn a Master of Public Health (MPH) degree with a concentration in epidemiology. Traditional master’s degree programs require another two to three years in school, but just like your bachelor’s degree, you can finish your MPH degree much faster with an accelerated degree program. Some MPH programs can even be completed entirely online in as few as 63 weeks!
While not required to have a successful career as an epidemiologist, some people with aspirations of landing high-level government jobs or directing large–scale research projects will also pursue a Ph. D. or medical doctorate in their chosen field.
Like any other long-term goal, becoming an epidemiologist can be broken down into a series of smaller steps, which can keep you on track and make the final outcome feel much more attainable.
Here’s a step-by-step guide to the education, experience, and certifications you’ll need to become an epidemiologist:
1. Enroll in a Healthcare-Focused Bachelor’s Degree Program
The first step in your epidemiologist training is enrolling in a bachelor’s degree program from an accredited college or university. To set yourself up for a career in epidemiology, you may want to consider a B.S. program focused on public health, or on adjacent fields like a Bachelor of Science in Health & Wellness or a Bachelor of Science in Healthcare Administration. While earning your bachelor’s degree requires both commitment and discipline, it’s a goal that’s achievable for just about anyone who’s willing to work for it. For example, to enroll in any of the healthcare bachelor’s degree programs at Brookline College, all you’ll need is a high school diploma or GED, plus a passing score on a Scholastic Level Exam and a computer literacy exam.
2. Earn Your Bachelor of Science Degree
To succeed as an epidemiologist, you’ll need a thorough understanding of public health issues and the various factors that contribute to them. That means earning a healthcare-focused bachelor’s degree can give you a major head start over other degree programs as you work toward your epidemiology career.
Like any bachelor’s degree program, you should expect to study a number of general-education subjects like math, literature, statistics, psychology, and communications. However, epidemiologists, in particular, will benefit from a well-rounded knowledge of science, math, and statistics, which will help you conduct sound research and gain better insights from public health data.
To solve the big-picture problems you’ll be tackling as an epidemiologist, you’ll need plenty of contextual knowledge about human health and behavior, as well as how healthcare facilities and programs work in the real world. Any bachelor’s degree program with a concentration in healthcare will likely include courses in everything from kinesiology to psychology to courses focused on health education and healthcare administration. Other classes will teach you leadership and management principles and how to use data and statistics in the context of public health issues. All these skills are vital for epidemiologists, who must balance leadership abilities with analytical insights that can only come from digesting massive amounts of detailed information.
3. Earn Your Master of Public Health (MPH) Degree
Almost all epidemiologists will need to earn a master’s degree of some sort, frequently a Master of Public Health (MPH) with a concentration in epidemiology. An MPH program is where you’ll polish the advanced leadership, analytical, and communication skills you’ll need to oversee research projects and data-analysis efforts that drive medical breakthroughs and public health policy.
Your public health master’s program will build upon your bachelor’s degree with courses focused specifically on epidemiology and related subjects like biostatistics. You’ll also complete courses that will teach you about environmental and occupational health, clinical effectiveness, and how to analyze and improve public health systems and policies.
At the end of your MPH program, you’ll need to complete an internship or practicum where you’ll apply the statistical and analytical methods you’ve learned to solve real public health problems. In addition to providing hands-on experience, this internship will help you polish your ability to gather and interpret the kind of data that epidemiologists depend on to do their jobs.
