About me
Since September 2023, I am the inaugural Edixhoven Postdoctoral Fellow at the Mathematical Institute of Leiden University. Previously, I was an Emily Erskine Endowment Fund Postdoctoral Researcher Fellow at the Einstein Institute of Mathematics of the Hebrew University of Jerusalem working with Ari Shnidman. Originally from Denmark, I grew up in France and have since then lived in Switzerland, USA, Canada, Israel, and the Netherlands.

Research interests
My interests lie in algebraic number theory and arithmetic geometry
with a special emphasis on modular forms, elliptic curves, algebraic cycles
and special values of L-functions.
I am also interested in rational points on higher genus curves.
