Michalik Daniel - 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 and should not be considered as a list of currenly active people on the Gaia mission. 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 overview papers (for Gaia Data Release 1 see here, for Gaia Data Release 2 see here, for Gaia Early Data Release 3 see here, for the full Gaia Data Release 3 see here, for Gaia Focused Product Release see here). A history of contributions to the Gaia mission can be found from the acknowledgements given with each data release.

ESA/ESTEC, The Netherlands
Daniel Michalik works as a research fellow at ESA/ESTEC. His projects focus on the scientific exploitation of the Gaia results.
In past research, Daniel adapted Gaia's core astrometric solution for marginal cases. Those are cases when sources are observed insufficiently much for a good-quality stand-alone astrometric solution. As part of his PhD thesis "Tycho-Gaia and beyond: Combining data for precision astrometry", he and his advisors invented the Tycho-Gaia Astrometric Solution (TGAS; image of the week; detailed description; quasar extension). He also studied general mathematical strategies for the generation and incorporation of different prior information in astrometric solutions (HTPM paper; generic approach and theory following Bayes' rule).
Daniel obtained his Masters degree in Computer Science at FAU Erlangen-Nuremberg (Germany). 2009/10 he worked as a Young Graduated Trainee at ESA/ESAC on LISA Pathfinder, Gaia, and synergies with Nano-JASMINE. In 2017, Daniel worked as on-site support astronomer for the South Pole Telescope in Antarctica, contributing to observations of the Cosmic Microwave Background (CMB) and of the event horizon around Sgr A* (Event Horizon Telescope; EHT/VLBI).
