My interests

Mathematics
Currently I am a 'wissenschaftlicher Assistent' at the University of Bonn. (Mathematisches Institut der Universität Bonn).

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

My other interests include: house plants, photography, gardening, wine making, travel, and rabbits. I am also a vegan, which means I do not eat or use meat, seafood, eggs, dairy products, honey, and just about anything else that has been derived from and/or tested on animals.

Go
I like to play the oriental strategy game go. 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.

Esperanto
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.
