I am a CNRS junior researcher (chargé de recherche) at the Équipe d'Analyse Fonctionnelle of the Institut de Mathématiques de Jussieu, Sorbonne Université. I also hold a Junior Research Fellowship at Trinity College, Cambridge. I am interested in metric geometry, geometric functional analysis, discrete analysis and probability.
I received a PhD from the Mathematics Department of Princeton University, where I worked under the supervision of Assaf Naor, and a BA in Mathematics from the University of Athens, Greece.
Here is my CV.
