I am an associate professor 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 keenly interested in computational aspects of both number theory and algebraic geometry.

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

Anna Medvedovsky and I taught a short course on Galois representations and modular forms at the Introduction to SAGA research school at Luminy in early 2023.

Chenyan Wu and I organised the 2020 Number Theory Down Under meeting.
