Gilles Weymann-Despres Post-doc Université d'Oxford

Présentation

I am a postdoctoral research associate in the Department of Astrophysics at the University of Oxford.My work focuses on analysing data from the polarized cosmic microwave background to study the early Universe and the mechanisms of cosmic inflation.
