Hi!
I am a Ritt Assistant Professor (postdoc) in the math department of Columbia University. Prior to that I spent one year in ENS Lyon working with Alice Guionnet. I graduated in November 2022 from Université Paris Dauphine where I did my PhD under the co-supervision of Djalil Chafaï (Université Paris Dauphine) and Sylvia Serfaty (New York University).
My research lies in probability theory with a special focus on statistical physics. Today, I am particularly interested in Coulomb gases and the Kosterlitz-Thouless phase transition, spin glasses, random matrices and renormalization.
Here is a brief CV.
