## About

### Overview

Dr Cox studied at Clare College, Cambridge (1990-4), and graduated with a BA(Hons) degree in Mathematics, followed by a Certificate of Advanced Study in Mathematics. He spent the next three years preparing his PhD at Queen Mary and Westfield College, University of London, graduating in 1997.

After working in Oxford, Stuttgart, and Bielefeld, he joined the Mathematics Department in 1999. He is currently Head of Department.

Dr Cox's research interests lie in representation theory, where he studies representations of algebraic groups and related algebraic objects. Recent collaborations have involved researchers in Australia and China, as well as at City and elsewhere in the UK.

Dr Cox is a member of the Representation Theory research group in the Centre for Mathematical Science.
