Epidemiologists play a vital role within the health sector, working alongside healthcare professionals, researchers, policymakers, charities and community groups.

The role of epidemiology is essential in the realm of public health. It helps reveal the cause and frequency of diseases and health events in human populations. Epidemiologists analyse data, conduct research and implement evidence-based strategies that help save lives, promote health and elevate quality of life.

Australia is renowned for its cutting-edge research facilities and top-notch healthcare system, where aspiring epidemiologists have a thriving environment to excel. With a booming job market and promising growth prospects, the field of epidemiology presents an exciting opportunity to make a tangible impact on public health.

This article explores the world of epidemiology. We discuss the job profile, the skills required, roles and responsibilities, academic requirements and career opportunities. We also shed light on the potential salary and earnings prospects. If you have ever wondered, “what does an epidemiologist do?” you’ll find your questions answered here.

What is epidemiology?

Epidemiology is a field that includes medicine, health sciences, social sciences, statistics and data analysis. It’s the art and science of investigating and understanding the patterns, causes and effects of health events in communities.

From studying infectious outbreaks to examining the impact of lifestyle choices on chronic conditions, epidemiology allows us to peer into the intricate web of health and disease, paving the way for evidence-based interventions and policies that save lives and enhance the quality of life for communities.

What is an epidemiologist?

Epidemiologists study the cause and prevalence of diseases and major health events such as the COVID-19 pandemic. The study and research of illnesses help government officials and health policymakers plan and execute strategies to minimise transmission.

By unveiling disease patterns, epidemiologists hold a pivotal role in public health. These disease detectives analyse data, conduct research and interpret trends to identify risk factors and develop effective prevention strategies.

In collaborating with diverse stakeholders, including healthcare professionals, policymakers and community organisations, epidemiologists forge evidence-based recommendations and policies to curb disease spread and foster healthier communities.

From hospitals to community health centres and government agencies to non-profit organisations, epidemiologists thrive in varied settings, addressing societal health challenges like chronic diseases, infectious outbreaks and health disparities.

What are the roles and responsibilities of an epidemiologist?

Epidemiologists shoulder a wide range of responsibilities in their mission to prevent and control disease, from conducting research and analysing data to advising on public health policies.

Epidemiology jobs involve these key roles and responsibilities: 

  • Research: Designing and implementing epidemiological studies and surveys, collecting information to help unravel disease patterns and causes and employing statistical techniques to interpret epidemiological data, assess interventions and communicate findings through reports and presentations.
  • Surveillance and monitoring: Tracking disease trends, establishing surveillance systems and collaborating with healthcare providers and laboratories to ensure timely reporting.
  • Outbreak investigation: Responding to infectious disease outbreaks, collecting human blood and tissue samples, investigating sources and transmission patterns and implementing control measures.
  • Expert guidance: Advising policymakers, healthcare professionals and community organisations on evidence-based strategies, participating in policy development and promoting health literacy.
  • Collaboration and networking: Engaging with colleagues, health professionals and organisations, attending conferences and fostering partnerships for health initiatives.
  • Public education: Educating the public about ways to preserve and enhance health. High-profile organisations focusing on epidemiology and public health include the World Health Organization and the US-based Centers for Disease Control.

As an epidemiologist, your responsibilities can vary based on your focus area and work environment. Whether you’re tackling infectious diseases, chronic conditions or environmental health, an unwavering dedication to improving public health remains paramount.

Most epidemiologists work standard business hours. Some overtime or irregular hours may be required when dealing with public health emergencies.

Four steps to becoming an epidemiologist in Australia

Embarking on a career as an epidemiologist in Australia is an exciting journey with a lasting impact on public health.

If you intend to study epidemiology full-time, a bachelor's degree will take four years, plus another two years for a master's degree.

The skills and personal characteristics you will need include curiosity, inductive reasoning, critical thinking, computer literacy, problem-solving, mathematical proficiency, an aptitude for research and analysis and the ability to work independently or as part of a team.

Follow these four steps to build a successful career in epidemiology:

1. Reflect on your career choice

Consider whether epidemiology aligns with your interests and values. Embrace the rewarding career while acknowledging the challenges and years of study required.

2. Complete an undergraduate degree

The typical entry point is a bachelor's degree in a relevant field like public health or health science. Epidemiology courses are not offered at an undergraduate level. Learning broad skills and knowledge in an undergraduate health course can put you in a position to complete a postgraduate epidemiology course.

3. Complete a postgraduate degree

Many aspiring epidemiologists choose to pursue postgraduate degrees, such as the University of Technology Sydney’s Master of Public Health or Victoria University’s Master of Public Health Major in Data Analytics. GlobalHealth Education offers a range of online public health courses to expand your knowledge and boost your career prospects. After completing your master's degree, consider becoming a member of the Australasian Epidemiological Association (AEA) to gain access to a fortnightly email bulletin with news and updates, attend an annual scientific meeting and participate in specialist interest groups.
