I am Professor of Mathematics at the math department (Institut für Experimentelle Mathematik) of the Universität Duisburg-Essen.

My main research interests are in the area of algebraic geometry and automorphic forms, in particular the bad reduction of Shimura varieties.


I like to play the oriental strategy game go (but did not get around to playing very much, recently). One can learn the rules in a few minutes, but it is a very complex game, with endless tactical and strategical possibilities.

I have written a go database program (Kombilo) and a program to practice solving go problems (uliGo). Check out the link above.


I learnt Esperanto, the international language, when I was a teenager, and have been quite active in the german Esperanto youth association for several years.

Unfortunately I don't have much time for Esperanto lately. Let me just give you some links: Universala Esperanto-Asocio, Tutmonda Esperantista Junulara Organizo, Esperanto in Germany, Esperanto in the US.


Another recent project: igelgrafik.de, a turtle graphics implementation based on CoffeeScript for use in the web browser.
