Just a couple of links for the moment...
Since 1998, I have been working for
ConSol* Software GmbH, after many years as
a research assistant at the Zentrum Mathematik of the Technische Universität München.
For some mathematical work, jointly with Pieter Moree, see the Number-theoretical constants page.
For some glimpses of what I spend my spare hours on, see my Astro-drawings pages (to be extended).
