Broadly speaking I am interested in the structure and representation theory of finite groups, and in combinatorial objects upon which such groups may act. Within these areas I am interested in developing computational algorithms and techniques for computing with concrete examples, especially when these examples seem out of reach of the existing methods and technology.

I’ve also got a bit of a side-line in static program analysis. Just for fun.

Find me on MathSciNet (if you have access to it).

Here are some things I am working on:

I enjoy seminars in the school, including the London Algebra Colloquium, the Monday pure mathematics seminar, sometimes the dynamical systems seminar, and the representation theory study group where I regularly contribute.

I also enjoy conferences! Maybe you’ve seen me at one.

Sometimes I make websites for people.

More stuff.

I have finally been ejected into the private sector where I am Head of Spend Analysis. I made a carbon footprint analysis thingamajig too.
