Education :

Victor Bonjean obtained his B.Sc. in fundamental physics from the Université de Bordeaux and his M.Sc. in Astrophysics from the Observatoire de Paris, completing his studies in 2016. He obtained his Ph.D. in Astrophysics ans Cosmology from the LERMA (Observatoire de Paris, PSL) and the Institut d’Astrophysique Spatiale in September 2019, under the supervision of Philippe Salomé and Nabila Aghanim. His thesis is entitled « Matter in the largest structures of the Universe : from galaxies to filaments, observations and data analysis ».

Career :

He has done a first post-doc at SISSA in Trieste on the data analysis group with Roberto Trotta in 2020, then he joined the Instituto de Astrofisica de Canarias in Tenerife, Canary Island as a member of Euclid in 2020/2021 with Helmut Dannerbauer and Carlos Gutierrez. In 2023, he joined a project outside of astrophysics to work as a research engineer on oceanography in LIENSs in La Rochelle (France) with Mélanie Becker. Since 2024, he has been a postdoctoral researcher at FORTH under the supervision of Jean-Luc Starck and Panagiotis Tsakalides in the TITAN team.

Interests :

His main interests are cosmology in general and has mainly focused on the properties of the matter (both gas with Sunyaev-Zel’Dovich effect and galaxies with large surveys) around the largest structures of the Universe such as cosmic filaments and galaxy clusters. He is interested in the development of statistical tools that can help in nowadays challenges in cosmology, and especially in image component separation from satellites of telescopes with deep learning networks and other state-of-the-art methods.
