About me

I am a postdoctoral researcher at University of Birmingham working with Andrew Treglown. Previously, I did my Ph.D. in Hamburg under the supervision of Mathias Schacht. Before that, I wrote my master's thesis at Universidad de Chile under the supervision of Maya Stein.

I'm interested in extremal and probabilistic combinatorics, especially in problems for hypergraphs and finite sets.
