Genetics

Genetics is the science of heredity and variation, exploring how information encoded in DNA shapes the characteristics of every living organism. It is a discipline that has been transformed in recent decades by advances in genome sequencing, gene editing technologies and high-throughput molecular methods that allow researchers to read and manipulate genetic material with extraordinary precision. These developments have profound implications for human health, agriculture, biotechnology and our understanding of evolution and biodiversity.

At the University of Sussex, you will study a discipline that is genuinely fast-moving, with regular discoveries reshaping what we know about gene function, gene regulation and the relationship between genotype and phenotype. The programme includes a foundation year, which provides a solid grounding in biology and related sciences before you enter the main degree. You also have the opportunity for a sandwich year in industry or a year abroad, giving you flexible pathways to build practical and international experience.

Work placements are part of the programme too, so you can gain direct exposure to research or commercial genetics environments alongside your academic studies. You will develop skills in laboratory techniques, data analysis and scientific communication, learning to interpret experimental evidence and think critically about complex biological questions.

The subject develops particular habits of mind: careful experimental design, the ability to reason from molecular mechanisms up to whole-organism and population-level effects, and a comfort with probabilistic thinking. These transferable analytical skills are as valuable outside science as within it.

Genetics graduates are well prepared for careers in the life sciences industry, including roles in pharmaceutical and biotechnology companies working on drug discovery, diagnostics and genomic medicine. Research positions in universities and public institutes are a common destination for those who continue to postgraduate study. Other graduates move into areas such as forensic science, agricultural biotechnology, genetic counselling (with additional training) and science communication.

The breadth of contexts in which genetic knowledge is now applied means that the career landscape for genetics graduates continues to expand.
