About me

I am senior lecturer in pure mathematics at the University of Exeter. I was previously fellow and college lecturer in pure mathematics at St. John's College, Cambridge. Before that, I was stipendiary lecturer in pure maths at St. Hugh's College, Oxford. In August 2007, I finished as a graduate student in the mathematics department at Cornell University where my supervisor was Ravi Ramakrishna. For the 2006-07 academic year, I visited Cornelius Greither at Universität der Bundeswehr München, Germany. I am originally from Jersey in the Channel Islands.

Research Interests

Algebraic number theory and related topics, including: the equivariant Tamagawa number conjecture (ETNC), Iwasawa theory, Galois module theory, computational number theory, noncommutative Fitting invariants, and integral representation theory.

Graduate Course

Here are some rough notes from a graduate course I taught on Galois Modules. Comments and corrections welcome.
