I am a postdoctoral researcher in the Department of Mathematics (IRMA) at the University of Strasbourg. I completed my PhD with Andrea Seppi and Gérard Besson at Université Grenoble Alpes 2025 . My research is focused now on Teichmüller theory, geometric structures, and more specifically, anti-de Sitter and hyperbolic geometry.
