Research

I work on mirror symmetry, non-archimedean geometry, tropical geometry and derived geometry. I aim to build a theory of enumerative geometry in the setting of Berkovich spaces, which I call non-archimedean enumerative geometry. The theory will give us a new understanding of curve counting in Calabi-Yau manifolds, the structure of their mirrors, as well as the moduli space of Calabi-Yau pairs. It is also intimately related to the theory of wall-crossing structures and cluster algebras.

I am awarded the Clay Research Fellowship in 2016, and an ERC starting grant in 2020.
