I am a CNRS researcher (chargé de recherche) in the POEMS laboratory (CNRS, Inria, ENSTA) and the Applied Mathematics Department of ENSTA at Palaiseau (France) since October 2016. Previously, I have been a postdoctoral researcher at UCLouvain (Belgium), Rice University (USA) and VirginiaTech (USA). I received my PhD from ULiège (Belgium) in 2013 and my HDR from IP Paris (France) in 2024.
