About Me
I am currently doing a postdoc at the Denis Poisson Institute where I am working with Romain Gicquaud and Yannick Herfray. From September 2024 to August 2025, I was ATER (temporary research and teaching assistant) at the university Marie and Louis Pasteur (ex University of Franche Comté) where I worked with Nabile Boussaïd on dispersive estimates for the massive Dirac equation in the Schwarzschild spacetime. I did my PhD under the supervision of Jean-Philippe Nicolas at the University of Western Britanny, in the Mathematic Laboratory (LMBA). My thesis deals with the asymptotic behaviour of zero rest mass fields in radiative spacetimes and with the geometry of Vaidya and Robinson-Trautman spacetimes.
