Je suis actuellement "adjunkt " (position temporaire, équivalente à celle de "assistant professor") à l'université de Varsovie en Pologne. 

De septembre 2019 à juin 2023, j'étais maître de conférences à l'université Paris-Saclay. J'ai soutenu mon hdr en juin 2023

Auparavant (juin 2017-juin 2019) j'étais postdoctorant à l'Université Catholique de Louvain-la-Neuve où je travaillais avec Jean Van Schaftingen. D'octobre 2015 à avril 2017, j'étais post-doctorant à l'Université pontificale catholique du Chili (PUC) à Santiago du Chili. J'y ai travaillé avec Duvan Henao, dans un groupe dirigé par Manuel del Pino.

J'ai effectué ma thèse (septembre 2012- septembre 2015) à l'Université Paris-Est Créteil, sous la direction d'Etienne Sandier et Laurent Hauswirth.

I am currently an  "adjunkt" (equivalent of assistant professor) at the University of Warsaw.

From september 2019 to june 2023 I was a "maître de conférences" at the Université Paris-Saclay. 

Before that I was a post-doc researcher (june 2017-june 2019) at the Catholic University of Louvain-la-Neuve (UCL) in Belgium. I worked under the supervision of Jean Van Schaftingen. From october 2015 to april 2017, I was a postdoc at the Pontificia Universidad Catolica (PUC) of Santiago in Chile. I worked under the supervision of Duvan Henao  and in a group led by Manuel del Pino.

I did my PhD  (september 2012-september 2015) in mathematics at Paris Est Créteil University, under the supervision of Etienne Sandier and Laurent Hauswirth.

Research interest : Calculus of Variations, Partial Differential Equations, Phase transitions, Ginzburg-Landau model in superconductivity, Minimal Surfaces, Harmonic maps, Liquid crystals, Nonlinear elasticity.
