I am an assistant professor at Paris-Saclay University, working at Laboratoire de Physique des 2 infinis – Irène Joliot-Curie (aka IJCLab).
I am currently working in observational cosmology with the Simons Observatory. I have also worked in neutrino physics, looking for Majorana neutrino with the SuperNEMO experiment. I also contribute to and maintain some open source projects on GitHub.
