I work on non-archimedean geometry, tropical geometry and mirror symmetry. 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, as well as the structure of their mirrors. It is also intimately related to the theory of cluster algebras and wall-crossing structures. I am awarded the Clay Research Fellowship in 2016.
