Current Situation:
I am currently Chargé de Cours (Associate Professor) at the Mathematics Department of the Université Libre de Bruxelles. I completed my Ph.D in December 2014 at the University of Cergy-Pontoise under the supervision of O. Druet and E. Hebey. I was then a post-doc at the ULB from 2015 to 2018 under the supervision of J. Fine.
A full CV is available here.
Research interests: Nonlinear Analysis, Geometric Analysis, Einstein Metrics, Mathematical General Relativity
Since January 2026 I am an organizer of the Topical Activity Group (TAG) of the EMS Advancing in Nonlinear PDEs in Europe. Check our website for informations on events and conferences.
