Welcome to my page!

Since 2018, I am a junior researcher (CRCN) at Inria (Lille, France) within the project-team RAPSODI, headed by Claire Chainais-Hillairet. I am also a member of the Paul Painlevé laboratory (ANEDP team), mixed Université de Lille/CNRS unity.

In 2016-2017, I was a post-doctoral researcher at EPFL (Lausanne, Switzerland) within the chair, held by Assyr Abdulle, of Computational Mathematics and Numerical Analysis (ANMC). I have worked on numerical methods for problems with sign-shifting coefficients. In 2014-2015, I was a post-doctoral researcher within the CERMICS laboratory at École des Ponts ParisTech (Marne-la-Vallée, France). I have worked, as a member of the Inria project-team MATHERIALS, and jointly with Claude Le Bris and Frédéric Legoll, on questions related to computational homogenization. Since the end of my PhD, I have also been working, in collaboration with Alexandre Ern and Daniele A. Di Pietro, on arbitrary-order polytopal discretization methods, referred to as Hybrid High-Order (HHO) methods.

I obtained my PhD in December 2013 from Université Paris-Est (Marne-la-Vallée, France), under the direction of Robert Eymard, and the co-supervision of Daniele A. Di Pietro. I have prepared it in collaboration with IFP Énergies nouvelles, the national petroleum institute. As a PhD candidate, I was working on lowest-order polytopal discretization methods for the approximation of mechanical problems.

Research interests
