Research interests

I study the Einstein equations of general relativity. My general goal is to understand the long time behaviour (local/global existence, stability) of the solutions to the associated Cauchy problem. During my PhD (under the supervision of Jérémie Szeftel), I obtained results when part of the initial data for the Cauchy problem are prescribed on characteristic hypersurfaces. In my post-doc with Gustav Holzegel, I started working on the (in)stability of the Kerr-anti-de Sitter family of black holes.
