Since the epidemiological study definition is so broad, people get there from different pathways. Many epidemiologists start with a degree in public health. However, other science and medicine degrees can lead to an epidemiology career. For example, some RNs move on to epidemiology careers. Again, you have lots of options. The scope of epidemiology goes far. Since the aims of epidemiology go so far and wide, you can look for jobs in all kinds of places.
For example, you might conduct research in a university or a government research facility. Other medical professionals will use your research to treat and educate different populations. You might conduct clinical trials to determine the effectiveness and side effects of certain drugs. If you become a field epidemiologist, you can travel and treat effected populations directly. These are just a few of your potential career paths. The uses of epidemiology can be found virtually everywhere.
What Are the Uses of Epidemiology? What Does an Epidemiologist Do? Epidemiologists in this fieldwork to research the origins, treatment, and health outcomes of these diseases in the fight towards prevention. This includes physical factors like pollution or housing, as well as social factors like stress and nutrition. Environmental epidemiologists work to understand how different environments may result in physical or neurological outcomes, ranging from psychiatric to cardiovascular disorders.
Violence and Injury Epidemiology This epidemiological focus aims to address unintentional and intentional injuries across a lifespan. For example, epidemiologists in this field might focus their research on car accidents and work to identify the associated risk factors. Epidemiology centers around the idea that disease and illness do not exist randomly or in a bubble. Epidemiologists conduct research to establish the factors that lead to public health issues, the appropriate responses, interventions, and solutions.
By using research—from the field and in the lab—and statistical analysis, epidemiologists can track disease and predict its future outcomes. In the case of COVID, this analysis requires heavy data surveillance, collection, and interpretation.
Due to the scale and threat of the coronavirus pandemic, testing centers, and healthcare systems are required to report all related data, providing epidemiologists with a wealth of information upon which to base their studies. With this information, epidemiologists will track data including :. Using this data and more, epidemiologists create models that help predict the spread of the disease in the future—including where and when the spread may occur.
They may also be able to discern the most vulnerable populations likely to contract a disease and provide recommendations for intervention. In an attempt to stop the spread of disease and understand where it might go next, many public health workers use contact tracing to determine the connections of an infected person. By achieving a degree in epidemiology, you are poised to work in places such as local health departments, nonprofits, government organizations, academia, the pharmaceutical industry, and more.
Our graduates go on to work in roles at companies and organizations ranging in size, scope, and mission, such as:. The Department of Epidemiology at Columbia University Mailman School of Public Health is committed to producing world-class science with real-world impact while training the next generation of epidemiologists to improve the health and lives of communities around the world.
