Mathematical Sciences

Mathematics in the world, mathematics for the world.

With specialisms including pure and applied mathematics, data science, statistics, and actuarial science, maths at Essex has a broad reach.

From exploring the economic impact of cow social networks to the mathematical modelling of brain evolution to improve patient care; from solving scheduling problems at the Port of Felixstowe to leading the data revolution at the heart of London’s “Tech City” and the University’s pioneering work on Big Data – our research explores issues that have a real impact on people’s everyday lives and the world around us. This was recognised in the recent Research Excellence Framework, with 92.3% of our mathematical sciences research output recognised as world-leading or internationally excellent (REF 2021).

Maths graduates are always in demand due to the wide range of employers seeking their highly valued skills. Our degrees in mathematics, statistics, actuarial science and data science provide you with a fantastic platform to enter a range of interesting sectors. As a growing and influential department, we still make sure our staff and students know each other personally – we are a true academic family.

Whether you study at undergraduatepostgraduate or research degree level, you graduate with the Essex mindset that maths is far more than an academic discipline: maths is everywhere.

We are based in the university's new STEM Centre in the heart of Colchester campus. With our open door policy, collaborative workspace for students, and excellent staff-student relations, we pride ourselves on our reputation as a friendly and open department.
