About
Ingénieur de recherche du CNRS (SAPHIR ≈ émérite) à l'Observatoire de Paris, j'ai commencé ma carrière sur les aspects scientifiques du satellite astrométrique Hipparcos (1989-1993), d'abord sur son Catalogue d'Entrée, ensuite le traitement des données astrométriques, et finalement l'exploitation scientifique de ces données. Je suis depuis 1997 essentiellement investi dans la mission Gaia (satellite lancé le 19-12-2013, fin des opérations le 15-01-2025), tout d'abord la prospective scientifique, puis le traitement à bord du satellite, la simulation des données, puis la responsabilité de la validation des catalogues successifs, et je suis maintenant en charge du traitement des étoiles binaires ou multiples (CU4/NSS) de Gaia.
Mes intérêts scientifiques concernent notre Galaxie et ses étoiles, les systèmes binaires et multiples, et l'extinction interstellaire.
