Department of Mathematics


Our research is leading to real change in the world and making a difference to people's lives, from helping to feed the growing global population to predicting which areas in the world will flood next and ground-breaking modelling to predict local COVID-19 impact. We focus on five key areas:

Our research in REF 2021

We're delighted with our performance in the Research Excellence Framework 2021 (REF 2021).

The research performed in the Department of Mathematics (as submitted to UoA10-Mathematics) was assessed overall to be 35% world leading (4*) and 60% internationally excellent (3*). We are particularly pleased to see that 98.2% of our research outputs were considered either world-leading (41.8%) or internationally excellent (56.4%) - the Department of Mathematics is now within the top 20 UK Departments for quality of Mathematics outputs according to the Times Higher Education. This result correlates with an improved environment that is rated as 100% conducive to producing research either of world-leading or of internationally excellent quality. We have improved our research impact, with 83% now rated either outstanding or very considerable. Our Mathematics overall ranking by GPA rose from 39th to 26th in the UK, between REF2014 and REF2021, according to Times Higher Education.

Across the University of Sussex as a whole, 89 per cent of research activity submitted to REF 2021 was categorised as either ‘world-leading’ (40.6 per cent) or ‘internationally excellent’ (48.4 per cent).

The results of REF 2021 were published on 12 May 2022.
