Lorentz–Epstein surfaces and a Liouville action for positive curves
About
I am a mathematician at the Laboratoire J.A. Dieudonné at Université Côte d’Azur.
I obtained my PhD in July 2015 under the supervision of Jean-Marc Schlenker. In 2019, I became Assistant Professor in Nice. I was appointed junior member of the Institut Universitaire de France (IUF) in 2024. In 2026, I became full professor at Université Côte d’Azur.
My research interests include higher Teichmüller theory, Higgs bundles, Anosov representations, harmonic maps, pseudo-Riemannian geometry, minimal and maximal surfaces, and geometric structures.
