I'm a professor for medicine at the University of Applied Sciences in Ulm, teaching in the study course "Health Information Management". I'm a physician by training (specialized in microbiology, therefore well-acquainted with bugs and viruses of all kinds) who also likes to program. I started programming way back in my teens on the Atari 800XL and later on the Amiga 2000 (mostly in C), then stopped for a while after switching to PC/Windows, primarily because my studies didn't leave enough time.

I discovered Python a few years ago and was hooked immediately. Suddenly programming was fun again. Most of the stuff I've been writing has to do with data crunching, XML processing and so on. I picked up a little knowledge on regular expressions along the way, and that is the area I'm most active in here on StackOverflow.
