I am a Postdoctoral Research Associate at Princeton University.
In October I will start as a Research Fellow at St John's college, University of Cambridge.

I am interested in algebraic and arithmetic geometry.
More specifically, I enjoy thinking about the arithmetic of curves, abelian varieties and arithmetic statistics.
In my PhD thesis, I have shown how various results in arithmetic statistics can be unified and reproved using the theory of graded Lie algebras.
