About the course
As a biologist you explore the true science of life. There is an ongoing need for the application of biological research, and some of the greatest scientific accomplishments of the future are likely to result from this. We’re investigating bioengineering projects, the development of renewable resource, and the potential for genetics and genomics to revolutionise medicine and health.
The vast and diverse world of living organisms offers a huge range of potential for study and work, and at Essex we give you the opportunity to explore the impact of climate change on coral reefs, the biology of sporting achievements, and cancer and stem cell biology, to the development of new artificial blood products.
You have a large degree of flexibility in order to tailor your degree to your interests, whether they be cellular or molecular biology, or field-based ecological science. You can choose from a wide range of areas, including:
- Animal behaviour and ecology
- Plant biotechnology
- Coral reef ecology
- Cancer biology
You learn modern lab techniques, take part in specialist field trips, and play your own part in adding to the ever-growing knowledge within biological sciences.
“I chose to study BSc Biological Sciences at Essex because it’s a very broad course with lots of choice for optional modules. The thing I enjoyed most was the field trip to Indonesia, as it was interesting to experience another culture and see the diversity of coral reefs in the Indo-Pacific."
Matt Wilby, BSc Biological Sciences 2015
Our BSc Biological Sciences is approved by the Royal Society of Biology.

You apply this ecological knowledge to real-world problems, such as pest control and conservation.
Human activity is resulting in an ever-accelerating rate of extinction of biodiversity. Many species in the tropics are becoming extinct even before they have been described by science, while many more are threatened worldwide, including in the UK. Considering the need for biodiversity conservation, you work alongside some of the key employers in the sector including Essex Wildlife Trust and the Environment Agency. Topics include sustainable fisheries and agriculture, climate change, environmental law and captive breeding and re-introduction.
Our oceans cover 71% of the Earth’s surface and contain 97% of the planets water. This vast underwater world supports a huge diversity of living organisms – get to know them.
