I am a postdoc at Humboldt-Universität zu Berlin, funded by the ERC grant SYZYGY, working in the group of Gavril Farkas.

Previously, I spent a year as a postdoc at Universität Bonn, and I obtained my PhD in November 2021 from Universitat de Barcelona under the supervision of Martí Lahoz and Juan Carlos Naranjo.

My field of research is Algebraic Geometry, with a special focus on abelian varieties and their interaction with algebraic curves, derived categories and Bridgeland stability.
