I am a senior lecturer in Pure Mathematics at the University of Melbourne, in Australia. My research is in arithmetic algebraic geometry, an area at the intersection of number theory and algebraic geometry. I am also interested in computational aspects of number theory, algebraic geometry, representation theory, and other algebraic topics.

I am part of the Number Theory Group, and Number Theory Down Under.

We are organising this year's Number Theory Down Under meeting.
