Epidemiology benefits the population

Epidemiologist Charlotte Gilkison says it was her interest in population health rather than the health of individuals that led her to study epidemiology.

“I was thinking of doing medicine, but saw the benefit to society with epidemiology."

She says COVID-19 is a perfect example. "I’m now providing the Ministry of Health with intelligence to get a better idea of who is most at risk. It involves analysing data on all cases that get notified, such as gender, age, symptoms and location."

Being responsive to new disease outbreaks

“There are always new and emerging diseases happening in New Zealand and around the world so you have to be ready to shift priorities," says Charlotte.

"But usually we’re responding to a variety of diseases, such as vaccine-preventable or foodborne diseases. Sometimes several outbreaks can happen at once, which is challenging, but it’s all about teamwork."

Growing interest in Pacific diseases

For her Masters in Public Health, Charlotte got the chance to work on a project with a university in the Netherlands. “I learned how to use a leprosy transmission model and adapt it for Kiribati, where leprosy has been increasing.

“I’m now interested in the Pacific, and the big dream is to work with the World Health Organisation on tropical diseases.”

Entry requirements

To become an epidemiologist you need to:

  • complete a Bachelor’s degree in a biological or health science, or maths and statistics, and
  • complete a Masters or PhD in public health, majoring in epidemiology. 

Secondary education

A tertiary entrance qualification is required to enter further training. Useful subjects include maths, biology, chemistry, health, social studies, economics and digital technologies. 

Personal requirements

Epidemiologists need to be:

  • good at teamwork
  • able to think critically and observe patterns in statistical data
  • good communicators
  • accurate and detail-focused.

Useful experience

Useful experience for epidemiologists includes:

  • working with a large amount of data
  • experience in the health industry
  • experience in a statistics-related role
  • work on an epidemiological project. 


Employers prefer epidemiologists to be registered with the International Epidemiological Association.

What are the chances of getting a job?

Disease prevention focus creating demand for epidemiologists 

Demand for epidemiologists is expected to increase because of a growing focus on reducing the risk of ill health and disease in the New Zealand population.

It is recognised that health inequalities contribute to chronic (long-term) disease, and by analysing health data of specific groups, epidemiologists enable targeted health interventions. 

COVID-19 highlights epidemiology 

As epidemiologists have played a significant role in helping control the COVID-19 outbreak, demand for epidemiologists is likely to continue. 

Through Budget 2020 and the COVID Response and Recovery Fund the Government is investing over $400 million in science and innovation over four years. This is expected to create further opportunities for epidemiologists.   

The funding will assist epidemiologists working in other areas including:

  • water and environmental monitoring
  • food safety
  • new foods
  • vaccines (for diseases other than COVID-19)  
  • biofuel production.

Applied public health experience valuable 

The expanding number of public health Master’s degree programmes has led to more graduates with epidemiology qualifications and more competition for jobs in some areas.

However, experience in an applied public health setting, for example at the Ministry of Health or a public health unit, will allow you to gain analytical skills valued by many employers.

Types of employers varied

Epidemiologists may work for:

  • public health units
  • the Ministry of Health  
  • Crown research institutes (CRIs)
  • universities
  • medical and veterinary laboratories
  • hospitals
  • commercial science laboratories
  • private research institutes.
