He obtained a B.A. degree (Parts I & II) in Mathematics at Trinity College, Cambridge, where he was Senior Wrangler (achiever of the highest mark), and went on to complete the C.A.S.M.. He then completed his dissertation, entitled The levels of modular representations, under the supervision of Richard Taylor, for which he was awarded a Ph.D. degree.
He took a lectureship at Imperial College London in 1998, a readership in 2002, and was appointed to a professorship in 2004. From October to December 2002 he held a visiting professorship at Harvard University, having previously worked at the Institute for Advanced Study, Princeton (1995), the University of California Berkeley (1996-7), and the Institute Henri Poincaré in Paris (2000).
He was awarded a Whitehead Prize by the London Mathematical Society in 2002 for "his distinguished work in number theory", and the Senior Berwick Prize in 2008. While attending the Royal Grammar School, High Wycombe he competed in the International Mathematical Olympiad, where he won a bronze medal in 1986 and a gold medal with a perfect score in 1987.
He was notably advisor to the musician Dan Snaith, who records as Caribou. His favourite number is 59.
