Research highlight
    I participated as a lecturer to the online Winter School on "Spectral Methods for Complex Systems" (January 2019) where I give an interlocutory talk (videos and slides are available) about spectral analysis in finite and infinite dimensional dynamical systems.

    I recently worked on two papers on Thermostatic Controlled Loads (TCLs), showing effects of the disorder (meaning non identical TCLs) and the effect of a realistic Mean Field control. Basically, both effects greatly improve the resilience of ensemble of TCLs, making them more suitable for Demand Response.

    For another project on synchronization I work on the effect of delay in the Kuramoto model:

 Educational Background/Employment:
  • Physics/Chemistry B.S. (2009 - 2011), "Classe Préparatoire aux Grandes Écoles" (Paris, France)
  • Physics B.S. (2011 - 2012), École Normale Supérieure de Lyon (Lyon, France)
  • Physics M.S. (2012 - 2014), École Normale Supérieure de Lyon (Lyon, France)
  • Physics Ph.D. (2014 - 2017), Laboratory of Mathematics J.A. Dieudonné (Nice, France)
  • Employment:
    • CNLS/T-4 Postdoctoral Research Associate, Los Alamos National Laboratory (November 2017 - Now)

Research Interests:

  • Statistical Physics; Nonlinear Physics; Out-of-Equilibrium Physics
  • Bifurcation in Kinetics Systems:
    ○ BGK Plasma instabilities (through Vlasov-Poisson equation)
    ○ Astrophysics instabilities (through Vlasov-Newton equation)
    ○ Dimensional reduction of bifurcation (from Vlasov to a reduced model)
    ○ Synchronization in coupled oscillators systems (through Kuramoto model)
  • Coulombian model for very large Magneto-Optical Trap
  • Thermostatic Controlled Loads: control of a large aggregate via mean field coupling
