Biology is the scientific study of life and living organisms, from microscopic cells and DNA to complex ecosystems. It seeks to answer fundamental questions about how life functions, evolves, adapts, and interacts with the environment. Whether it's understanding how diseases spread, discovering new medicines, protecting endangered species, or exploring the human genome, biology sits at the heart of many of today's most important scientific breakthroughs.
Unlike disciplines that focus on a single aspect of science, biology spans multiple levels of life — from molecules and cells to organisms, populations, and ecosystems. It also increasingly overlaps with chemistry, physics, mathematics, computer science, and engineering, making it one of the most interdisciplinary sciences available today.
Biology is well suited to students who are naturally curious about the living world, enjoy asking questions, and are excited by discovery, research, and solving real-world challenges. Whether your interests lie in healthcare, environmental conservation, biotechnology, or scientific research, biology provides a versatile foundation for a wide range of careers.
A biology degree combines theoretical knowledge with hands-on scientific investigation. Students develop a strong understanding of living systems while learning to design experiments, analyse data, and apply scientific methods to real-world problems. Most programmes include laboratory practicals, fieldwork, and research projects. Expand each topic to learn more.
The skills you graduate with
A biology degree develops a broad range of scientific, analytical, technical, and professional skills that are valued across many industries — not only in research and healthcare, but also in technology, consulting, education, and policy.
Laboratory techniques
Hands-on experience with microscopy, cell culture, genetic analysis, molecular assays, and modern biological instrumentation.
Scientific research methods
Designing experiments, formulating hypotheses, collecting and interpreting biological data, and drawing evidence-based conclusions.
Data analysis
Statistical reasoning, quantitative analysis, and bioinformatics — using computational tools to interpret large biological datasets.
Critical thinking
Evaluating scientific literature, identifying assumptions, and constructing well-reasoned arguments from experimental evidence.
Scientific communication
Writing research reports, interpreting findings for different audiences, and communicating complex biological concepts clearly.
Collaboration and ethics
Working in research teams, managing projects, and applying ethical reasoning to biological research and its real-world implications.
Where this degree takes you
A biology degree opens pathways into research, healthcare, biotechnology, pharmaceuticals, environmental science, agriculture, public health, and many emerging interdisciplinary industries. Graduates work in both laboratory and non-laboratory settings, applying biological knowledge to scientific discovery, healthcare innovation, sustainability, and technology. The careers listed here are a selection of common pathways — they are not exhaustive, and the field continues to expand.
The careers listed here represent some of the most common pathways for biology graduates — they are not a comprehensive list. Many graduates also move into science communication, education, regulatory affairs, policy, healthcare management, and postgraduate study in areas such as genetics, neuroscience, biotechnology, public health, and medicine.
Who tends to thrive here
Biology is a strong match for students who are fascinated by living organisms and how life works — who enjoy science, ask questions about the natural world, and like solving problems through observation, experimentation, and research. If you are interested in healthcare, biotechnology, sustainability, or scientific discovery, and you enjoy both laboratory work and analysing data, biology provides a versatile and rewarding foundation.
Strong performance in Physics, Chemistry, and Mathematics is important preparation for a biology pathway. University-level biology draws heavily on chemistry for understanding biochemical processes, on physics for topics such as biomechanics and imaging techniques, and on mathematics for statistics, modelling, and quantitative analysis. Students who genuinely enjoy these subjects and are comfortable working across all three will find the transition to university biology significantly smoother.
Biology is also becoming increasingly interdisciplinary. Success in the field increasingly comes from combining biological knowledge with skills in computing and data analysis alongside the core sciences. Students who enjoy connecting ideas across different scientific disciplines are particularly well positioned for the future of this field.
If you are more interested in designing medical devices or engineering solutions, Biomedical Engineering may be a better fit. If your primary interest is diagnosing and treating patients, Medicine or Allied Health Sciences may be worth exploring. Students drawn to ecosystems and environmental policy might also consider Environmental Science as an alternative pathway.
