Welcome to my web site

I studied mathematics as an undergraduate at London University, and then went to Oxford University as a research student in the Mathematical Institute, and was awarded my DPhil in 1980.

Something I really love is having a long walk along the coast of Cornwall, which is lucky, because I live there. I also enjoy choral singing, and I have a private pilot's licence, which reminds me of how much I enjoyed flying when I could afford it!

I am the General Secretary of the London Mathematical Society, having served as its Programme Secretary from 2001 to 2011. I was also the Secretary of the European Mathematical Society from 2007 to 2014.

My research interests are in graph theory, twistor theory, and the history of geometry, and I also have a variety of mathematical consultancy work.

Finally, here are links to my articles, books, and my teaching interests.
