Main Research Fields

I am an astronomer, working on constraining galaxy evolution from an observational point of view, by making use of large-scale, ultra-deep multi-wavelength surveys of galaxies. I am notably interested in understanding why and how galaxies can eventually stop forming stars across cosmic history.

I studied physics in Marseille (France) and did my PhD in astrophysics and cosmology at LAM (Laboratoire d'Astrophysique de Marseille, Aix-Marseille University), working in particular on the photometric strategy for galaxy properties estimation in support to ESA's Euclid mission. After working on the scientific exploitation of galaxy large-scale surveys combining ground- and space-based multi-wavelength observations (GALEX, CFHT, Subaru, VISTA, Spitzer), I started leveraging the exquisitely deep and sharp view of galaxies that the unparalleled synergy between HST and JWST gives us across cosmic time. I am also involved in the preparation of forward-looking instruments such as MOSAIC/ELT, which will allow us to leverage forthcoming ELT's giant mirror to further characterise the physics at play within primordial galaxies.

Currently an ESA Research Fellow at the European Space Astronomy Centre (ESAC) near Madrid (Spain), my research focuses on galaxies fate, through the study of the connection between the growth of cosmic large-scale structures and their star-formation history, from the formation of their first stars at cosmic dawn to the lasting --if not definitive-- suppression (or quenching) of their star formation. To that aim, I can take advantage of the most comprehensive galaxy surveys ever conducted, by combining ongoing and forthcoming observations with JWST and Euclid, in order to probe galaxy evolution since the time when the first galaxies formed, about 13 billion years ago.
