Current Situation

Since February 2018 I am a Premier Assistant (tenured position, equivalent to Associate Professor) in the Analysis Group of the Université Libre de Bruxelles (ULB)

From September 2015 to January 2018 I was a post-doc in the Geometry group of the Université Libre de Bruxelles, under the supervision of Joel Fine. 

From September 2011 to August 2015 I prepared my Ph.D at the University of Cergy-Pontoise under the supervision of O. Druet et E. Hebey

Research Interests

Nonlinear Analysis -- Riemannian Einstein metrics -- Constraint equations in General Relativity

Curriculum Vitae

In English, with a list of the talks I have given and a teaching record. Link.
