Ulrich Bastian - Gaia
Astronomisches Rechen-Institut, Heidelberg
Uli Bastian is staff astronomer at ARI, Heidelberg, where he co-authored the FK5 and PPM star catalogues. He entered the Hipparcos project in 1983, when the preparations for the data treatment had just started. He mainly worked on the Tycho data reduction, but contributed to the Input Catalogue and the main-grid reductions as well. After having been one of the proponents of DIVA for a few years, he is fully with Gaia since 2002. He is a member of the Gaia Science Team, is leading the preparations for the `First Look' processing and has recently accepted the coordination of the `Core Processing' part of Gaia's data reduction.
Uli's scientific hobbies include variable stars, galactic structure, the popularisation of astronomy - and field research on butterflies. His most active non-scientific hobby is dancing, especially Argentine tango.
