Présentation

I am a researcher at Laboratoire EM2C (CentraleSupélec, Paris-Saclay University), specialized in the modeling of nonequilibrium plasmas for aerospace and energy applications. My work bridges the gap between fundamental plasma physics and engineering applications. My research focuses on three primary areas:

  • Aerospace Re-entry: I develop collisional-radiative (CR) models to predict the extreme heat loads spacecraft face during planetary entry. This involves simulating the population of radiative quantum states of gases such as N and N₂ in the afterbody wake of a vehicle, with the aim of improving thermal protection designs.
  • Nanosecond Discharges: I study the chemistry and hydrodynamics of Nanosecond Repetitively Pulsed (NRP) sparks.
  • Advanced Radiation Modeling: I develop high-accuracy Non-Local Thermodynamic Equilibrium (NLTE) radiation models for diatomic and polyatomic molecules. My expertise includes implementing Line-by-Line (LBL) approaches and Statistical Narrow Band (SNB) models to simulate complex radiative transfers in high-temperature gases.

Collisional-radiative models:

Line-by-line radiation models:

Reduced-order models for nanosecond discharges and post-discharges:
