Lebranchu Christian - Gaia
Gaia was proposed in 1993 and since then, many people have been involved in the Gaia mission, whether at ESA, at industry side or at one of the institutes involved in the Gaia data processing. The Gaia Data Processing and Analysis Consortium (DPAC) is a collaboration which consists of around 450 scientists and engineers.
The list of Gaia contributors presented here should not be considered a complete representation of the entire consortium and should not be considered as a list of currenly active people on the Gaia mission. A more complete list of Gaia contributors that were involved in the creation of the Gaia catalogues can be obtained from the author lists of the Gaia Collaboration overview papers (for Gaia Data Release 1 see here, for Gaia Data Release 2 see here, for Gaia Early Data Release 3 see here, for the full Gaia Data Release 3 see here, for Gaia Focused Product Release see here). A history of contributions to the Gaia mission can be found from the acknowledgements given with each data release.

Christian Lebranchu graduated in mechanical design in 1980 and obtained an engineering degree in 1991. He joined Matra-Espace (now Astrium) in 1982 and worked in mechanical engineering and procurement for several projects including Hipparcos, SOHO, MetOp, and Mars-Express. He then became mechanical/thermal/propulsion architecture department head for Science and Earth observation missions at Astrium Satellites in Toulouse.
Christian took part in the Gaia implementation phase proposal, and since then is responsible for the mechanical package and launcher interface coordination as assistant project manager in the Gaia industrial team.
In his free time, Christian breeds dogs, maintains his old farm, and enjoys trekking, photography, and astronomy.
