I am a lecturer in the School of Mathematics and Statistics at the University of Sheffield.
After a three-year period as Director of Teaching, I will be on leave for the academic year 2012–13.
I was Director of Teaching from September 2009 until September 2012. The new Director of Teaching is Prof Koji Ohkitani.
My field of research is algebraic number theory and algebraic geometry; in particular, I am interested in the theory of modular forms and Galois representations. More details can be found on my main maths page, which also contains some references to my papers.
