Blomme Ronny - 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.

Royal Observatory of Belgium
Ronny Blomme obtained his PhD in 1990 at the Vrije Universiteit Brussel. He is a staff member of the Royal Observatory of Belgium since 1989.
His main research interest is the stellar winds of massive stars. He observes these using both ground-based facilities (mainly radio telescopes) and space-borne ones. He studies how both small-scale and large-scale structure affect the stellar winds, and what happens when two of these winds collide in a binary system. He also uses hydrodynamics codes and develops radiative transfer codes to interpret the observed data. He is involved in the Gaia-ESO Survey, where he leads one of the working groups.
Ronny's Gaia involvement started in 2006. He develops one of the codes to determine the radial velocity from the RVS spectra and tests the scientific validity of such codes. He also works on the astrophysical parameter determination of hot stars.
