My interestes lie in algebraic geometry and combinatorics.

More specifically, I enjoy combinatorial problems arising in the theories of algebraic surfaces, tropical geometry and toric varieties. Recently, I have also been interested in positive geometries and other aspects of positivity.

Starting November 2023, I will be a fwo PhD fellow.
