Présentation

Current position : Associate Professor (Maître de Conférences) of University of Versailles (UVSQ) since September 2013

I received a Ph.D in Applied Mathematics from Claude Bernard University (Lyon 1) in 2011. I am assistant Professor and affiliated in Maison de la Simulation and LI-PaRAD laboratory where I am a member of the HPC Team. I authored 25 papers in international journals and conferences since 2010. I co-advised 1 Ph.D (2018). My main researches concern numerical linear algebra, parallel solvers and preconditioners, multilevel methods, and their application in the simulation of physical phenomenon. Since 2014 I also study software engineering for HPC and work on YML and multi-SPMD programming models. From 2018 to 2021, I am visiting scientist in the Programming Environment Research team in Riken R-CCS (Kobe, Japan).

I am in charge of the first year of the program MCHPS Msc in UVSQ (2014-2017)(2019-)

Research interests :

  • Numerical Linear algebra
  • Domain decomposition methods
  • Parallel solvers and preconditioners
  • High performance computing
  • Software engineering for HPC
  • Numerical simulation of physical phenomenon (CFD, environment)

Teaching :

  • Numerical algorithms (Msc)
  • Software engineering (Bachelor / Institut Universitaire de Technologie)
