Research
Representation theory of finite groups, especially modular representation theory.

My main focus at the moment is on Donovan's conjecture and the classification of Morita equivalence classes of blocks of finite groups. Because of work with Kessar, Külshammer and Sambale, Donovan's conjecture is known for 2-blocks with elementary abelian defect groups, that is, there are only finitely many Morita equivalence classes of such blocks. This opens the question of classifying the Morita equivalence classes.

The above research is funded by EPSRC grant Morita equivalence classes of blocks.

Block library

I have just set up this wiki site for cataloguing blocks of finite groups up to Morita equivalence and recording progress on Donovan's conjecture. If you would like to contribute, then please let me know.

Teaching
I will be teaching MATH10202 Linear Algebra A in semester 2 with Mark Kambites.
