My research concerns problems related to the Birch and Swinnerton-Dyer conjecture, and its generalisation to abelian varieties. I am particularly interested in the parity conjecture, which asserts that the Birch and Swinnerton-Dyer conjecture correctly predicts the parity of the rank. With this in mind, I spend a lot of time trying to compute the parity of ranks of Jacobians of curves, using the arithmetic of curves over local fields.
