Communicating science to the general public 

Becoming a spokesperson on how to stay safe during the COVID-19 pandemic wasn’t a role microbiologist Siouxsie Wiles (or the pink-haired science lady) expected to play. But she believes it's important for scientists to effectively communicate information to non-scientists.

“It’s been amazing to use my skills in this way because I love demystifying science and as scientists we all want our research to be useful,” she says.

Variety of infectious diseases projects

As a microbiologist specialising in infectious diseases, Siouxsie is involved in a number of projects.

“I’m looking at the genetic information of bacteria to see how they adapt and become more infectious. “By making them glow in the dark in the University of Auckland's bioluminescent superbugs lab, it’s easier to study them and get a better understanding of how to stop them causing disease.”

She’s also involved in finding new antibiotics from New Zealand fungi.

“Some of these experiments you can be working on for years, so it can be a really slow process of discovery.” 

Growing fascination with microbiology

Discovering microbiology began early for Siouxsie.

“I was a keen reader and remember the first spark came from reading Robert Wilkin’s ‘The Fireside Book of Deadly Diseases’. I was so fascinated that such small creatures could affect our bodies and our entire lives that I just wanted to keep learning.”

Entry requirements

To become a microbiologist you need to have a Bachelor of Science majoring in microbiology, biotechnology, biochemistry or molecular biology. 

A postgraduate qualification, such as a Master's degree or Doctorate, is usually required for research-based positions.

Secondary education

A tertiary entrance qualification is required to enter further training. Useful subjects include biology, maths, chemistry and physics. 

Personal requirements

Microbiologists need to be:

  • patient, persistent and inquiring
  • analytical, accurate and careful
  • motivated
  • innovative
  • able to communicate complex ideas simply.

There are a lot of biological safety regulations when working with infectious diseases. To be safe you need to follow rules and understand why you’re doing things a certain way.

What are the chances of getting a job?

Growing demand for microbiologists 

Demand for microbiologists is expected to grow as environmental regulations around water quality and food safety increase. There is also a growing demand for New Zealand scientists to produce new products that can be sold worldwide.      

According to the Census, 156 microbiologists worked in New Zealand in 2018.

Government funding supports range of microbiology projects

Through Budget 2020 and the COVID Response and Recovery Fund the Government is investing over $400 million in science and innovation over four years.

One of the Government’s priorities is supporting scientists to contribute to international efforts to create a novel coronavirus vaccine. This is expected to create further opportunities for microbiologists.   

The funding will assist microbiologists working in other practical areas including:

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

Commercial laboratory experience valued by employers    

Science graduates with some laboratory skills can expect to work as technicians or assistants before moving into more senior roles.

Employers prefer to employ microbiologists who have:

  • patience, perseverance and flexibility, and an eagerness to learn  
  • some experience working in a manufacturing or clinical laboratory
  • a strong customer focus and understanding of working to best practice.

Types of employers varied

Microbiologists may work for:

  • Crown research institutes (CRIs)
  • universities
  • medical and veterinary laboratories
  • hospitals
  • biotechnology companies
  • commercial science laboratories
  • agricultural product manufacturing companies
  • food manufacturing companies
  • private research institutes
  • breweries.
