I am a CNRS researcher (chargé de recherche) in the POEMS team (CNRS-ENSTA-INRIA, UMR 7231) at ENSTA Paris (Palaiseau, France), member of the Institut Polytechnique de Paris, since October 2016. Before, I have been a Postdoctoral Researcher at the Université catholique de Louvain (Belgium), Rice University (Houston, TX, USA) and VirginiaTech (Blacksburg, VA, USA). I obtained my PhD at the Université de Liège (Belgium) in 2013.

Open position (2021/2022) : Master internship (6 months) on discontinuous Galerkin methods for time-harmonic wave propagation at ENSTA Paris and LAUM — ANR WavesDG project   ⇒ Description (in french — english version upon request)

I am always looking for capable and highly motivated students (undergraduate and graduate) with backgrounds and interests in math, engineering, science to join my research program. Please contact me to discuss current opportunities.

Research interests:

  • Numerical simulation of wave propagation (acoustic, electromagnetic and elastic waves)
  • Absorbing boundary conditions and perfectly matched layers
  • High-order methods, discontinuous finite element methods and domain decomposition methods
  • High performance scientific computing and modern architectures
