My work is focused on the analysis of geometric hyperbolic partial
differential equations. More specifically, I am interested in the
Cauchy problem for the Einstein equations, in relation with the
following topics
Vacuum Einstein equations, Einstein-Vlasov, Einstein-Klein-Gordon system,
Structure and formations of singularities in symmetric solutions, loss
of global hyperbolicity,
Expanding solutions with weak regularity and their asymptotics,
Asymptotically Anti-de-Sitter solutions, linear wave equations on
asymptotically Anti-de-Sitter solutions, stability of asymptotically Anti-de-Sitter solutions.
Originally motivated by the study of the Einstein-Vlasov system, I have recently started working more on transport equations, including the study of linear kinetic transport operators and the Vlasov-Poisson or the Vlasov-Norström systems.
