What does a biologist do?

Biologists help us to understand environmental issues, genetics and the biology of animals and plants by studying all manner of living things and the world around them. Biologists work across a wide variety of sectors, including:

  • agriculture, where they might try to improve productivity in livestock or crops
  • conservation, supporting plants and animals in their natural environment, as well as addressing issues such as pollution
  • medicine, where they may develop new methods for diagnosing, monitoring and treating illnesses or disease
  • industry, by preventing food contamination or creating ways to dispose of waste safely

What do I need to do to become a biologist?

To become a biologist you will need to have an enquiring mind and good problem-solving skills. You will also need to work accurately and pay close attention to detail. Most employers will expect you to have a relevant degree and a master’s qualification. Some employers might also want you to have, or be working towards, a PhD.
