Eyer Laurent - 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. 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 papers (for Gaia Data Release 1 see here, for Gaia Data Release 2 see here, for Gaia Early Data Release 3 see here). A history of contributions to the Gaia mission can be found from the acknowledgements given with each data release.

Observatoire de Genève
Laurent Eyer obtained his PhD in 1998 at the Observatoire de Genève, Switzerland, working with Michel Grenon on the analysis of the variability data from Hipparcos, resulting in the Hipparcos Variability Annex and Light Curves (Volume 12 of the Hipparcos Catalogue). During his first postdoc, in the Catholic University of Leuven, he worked on exploiting Hipparcos findings on certain variable stars. A subsequent post-doctoral position at Princeton was focused on the analysis of the OGLE data, providing experience in the handling of massive data sets of direct relevance to Gaia.
Following the award of a major grant by the Swiss Government in May 2003 for involvement in the Gaia mission, Laurent Eyer returned to Geneva, where he led the Variability Working Group (2003-2005) whose goals were to develop the algorithms necessary for the automatic detection and classification of variable stars for Gaia. As a member of the DACC (2006) Laurent was involved in preparations leading to the formation of the Gaia Data Processing and Analysis Consortium. Within the DPAC he is manager of CU7: Variability Processing.
Laurent is involved with the European Leadership in Space Astrometry (ELSA) programme as the Scientist in Charge for Geneva Observatory and the Integral Science Data Centre.
