I'm a postdoc at Université de Rennes 1.
Previously, I was a postdoc at University College London, supported by an EPSRC Doctoral Prize Fellowship (EP/W524335/1).
I completed by PhD in 2024, at the University of Warwick, supervised by Prof. Samir Siksek and Dr Damiano Testa.
My research interests are in number theory and arithmetic geometry.
