## About

### Overview

Dr De Visscher studied at the Free University of Brussels graduating with a Licence in Mathematical Science in 1999. As part of her degree she spent one year as an Erasmus students at the University of East Anglia, graduating with a MSc in pure Mathematics in 1998. She prepared her PhD at the University of Oxford in 2000-2003. After working at Queen Mary College London, she joined City University London in 2005.

## Research

Dr De Visscher's research interests are in algebra, more specifically in the representation theory of algebraic groups and related finite groups and finite dimensional algebras. Her recent projects have been focusing on the representations of the (walled) Brauer and partition algebras and connections with the symmetric group.
