Aurélien Hees

Observatoire de Paris

Aurélien Hees obtained his PhD from the Université Catholique de Louvain (Belgium) in 2012. He subsequently did several postdoc at the NASA-Jet Propulsion Laboratory (USA), at the Rhodes University (South Africa) and at UCLA (USA).

He is currently Chargé de Recherche CNRS at SYRTE, Paris Observatory. His main research interests focus around the theory of General Relativity and its extensions. He is involved in the development of high accurate relativistic modeling required for future space missions and astrometric observations. He is also involved in the development and the data analysis of tests of the gravitation theory using observations performed at different scales in our Universe: within the lab with atomic clocks, around the Earth with Lunar Laser Ranging, Very Long Baseline Interferometry, GNSS satellites, at Solar System scales with space mission measurements, at galactic scales by using observations of short period stars orbiting our Galactic Center as well as at the cosmological scale.

Within Gaia, he is working on the development of gravitational tests using Solar System Objects observations (SSO's) and SSO's orbit determination.
