Els Sebastian - 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.

Sebastian joined the DPAC Project Office (PO) in October 2009 as Interface Engineer. The past five years he was working in the framework of the site selection for the Thirty Meter Telescope. Between 2004-2005 at Caltech and since then at the Cerro Tololo Inter-American Observatory in Chile. Before that, he worked in the adaptive optics team of the Isaac-Newton Group on La Palma. He studied Physics in Hamburg and Heidelberg and obtained a PhD in Astronomy in 2002 from the University of Heidelberg.
On 1 July 2013 Sebastian took on the position of Project Coordinator and Head of the DPAC Project Office at ESAC.
Apart from Gaia, his instrumentation interests are mainly in the areas of measuring optical turbulence and in adaptive optics. His scientific interests are in the areas of atmospheric physics and extrasolar planets.
