Bombrun Alex - 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.

European Space Astronomy Centre
Alex joined the Gaia project in 2007 after completing his PhD at Ecole des Mines de Paris. He worked at the Astronomisches Rechnen-Institut in the Center for Astronomy of Heidelberg University on sphere reconstruction methods, and collaborated with Lund Observatory to develop AgisLab and the conjugate gradient algorithm used in AGIS. In 2012, Alex went to Dresden University at the Lorhmann-Observatorium to study the impact of basic angle variations on the AGIS solution and to investigate some mitigation possibility such as VBAC. His research led him to construct and analyse a new family of pre-conditioners designed for global astrometry.
In January 2015, Alex moved to the Gaia Science Operation Centre at ESAC in Madrid to support the AGIS team processing the incoming data and computing the first astrometric solutions.
