Up until the end of 2010, I was a university lecturer in
mathematics (with the title of Professor of Mathematics) and a
tutorial fellow of Wadham
College. I was also Chairman of Mathematics. Thereafter I served briefly as Acting Head of the Mathematical,
Physical and Life Sciences Division, and then as Deputy Head. I am now President of the Clay Mathematics Institute and a Senior Research Fellow of Wadham College.
I was an undergraduate at Oxford, and returned in 1977 after
completing a Ph.D in the Mathematics Department at King's College, London
(under the supervision of F A E Pirani) and spending a brief period
as a postdoc in the Physics Department at Princeton, working for J A
Wheeler. I was Treasurer of the London
Mathematical Society until 2009.
