I am a Reader in Pure Maths at Queen Mary University of London. In recent years I have been teaching MTH6104 Algebraic Structures II, which is about to change its name and code to MTH6106 Group Theory. I am also the chair of the Undergraduate Exam Board for maths, and head of the Algebra and Number Theory group.

Some useful things:
- Representation theory of finite (especially symmetric) groups
- Real and complex reflection groups and their Hecke algebras
- Crystal bases and canonical bases for integrable highest-weight representations of quantum algebras
- Combinatorics of partitions
Other mathematicians (a completely arbitrary selection – don't be offended by either your absence or your presence on this list)
