I have now moved to Basel, this page is no longer maintained.

I study the arithmetic of elliptic curves over global fields (mostly function fields in positive characteristic), mainly by analytic techniques. For example, I've studied the asymptotic behaviour of one of their invariants (the Brauer-Siegel ratio) through estimates on the size of the special values of their L-functions.

Keywords: Elliptic curves over global fields, L-functions of elliptic curves (and explicit computations of those), Birch and Swinnerton-Dyer conjecture, estimates of special values of L-functions at s=1, Brauer-Siegel theorem and analogues.

Articles and preprints


I did my PhD thesis under the supervision of Marc Hindry at Université Paris Diderot. I defended my PhD in July 2016: here is the introduction (in English and in French) and the full text (in French).
