Research

I’m interested in the study of the partial differential equations (PDE) at the heart of general relativity: the Einstein equations. My research is twofold:

  • Construction of high-frequency solutions to the Einstein vacuum equations.
  • Stability of black holes as solutions to the Einstein vacuum equations.

Organization

From 2022 onwards, I’m organizing the Reading Group in General Relativity taking place each month at LJLL (Sorbonne Université) and CMLS (École Polytechnique).

  • The 2023-2024 program consists in reading various articles around shock formation in nonlinear hyperbolic PDEs.
  • The 2022-2023 program consisted in reading The linear stability of the Schwarzschild solution to gravitational perturbations by Dafermos-Holzegel-Rodnianski.
