Klioner Sergei - 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.

Sergei Klioner is one of the leading workers in the field of relativistic effects in astrometry at the micro-arcsec level. His 2003 Astronomical Journal paper on "A Practical Relativistic Model for Microarcsecond Astrometry in Space" is being used as one of the formulations for the Gaia relativistic development. Working at the Lohrmann Observatory, Dresden, with Michael Soffel, Sergei is an active member of the Gaia working group on relativity and reference frames.
