I’m a mathematician and teacher based at the University of Sheffield.
Here are some other ways you might know me:
- I’m from Guernsey, in the Channel Islands.
- I’m a committed trade unionist, and member of UCU, and have been on the committee of the Sheffield branch.
- I’m a longstanding volunteer with the UKMT, which provides mathematical activities for interested school students, including the British Mathematical Olympiad.
