I am a Ritt Assistant Professor (postdoc) in the Mathematics Department at Columbia University. Before that, I spent a year at ENS Lyon working with Alice Guionnet. I received my PhD in November 2022 from Université Paris-Dauphine, under the joint supervision of Djalil Chafaï (Université Paris-Dauphine) and Sylvia Serfaty (New York University).

My research is in probability theory, with a focus on statistical physics. I am currently interested in the Berezinskii–Kosterlitz–Thouless phase transition and in spin glasses.

Here is a brief CV.
