Curriculum Vitae
I am running my own small business by designing mathematical 3dmodels and related mathematical objects (see MOLabs.com).
I received my Ph.D. (computational algebraic geometry) from the Johannes Gutenberg University of Mainz (Germany) in 2005 (October).
After 6 months as a PostDoc at the RICAM research insitute (Linz, Austria), I moved to Saarbrücken (Germany) where I was FrankOlaf Schreyer's assistant until April 2013. Since then I am running my own business, selling mathematical objects, producing related software, and teaching related mathematics.
I spent the summer term 2008 as a visiting professor (,,VertretungsProfessor'') at Erlangen, and summer term 2011 as a visiting professor at Cologne.
