Software development:

I started my first experiments in software development in 1980 with a Commodore VIC 20. Later,  I "upgraded" to Commodore 64 and in 1986 buyed an Atari ST. All software development this time was closely related to electronic devices (e.g. using an electronic typewriter as printer, sampling and remixing of pop music with 8-Bit-A/D converter). During my studies in worked as a programmer at the Institute of Microelectronics at the Universtät des Saarlandes. During my PhD all theoretical results were supported by software written in C and C++. And still during my current job I am very close to software development (mainly Java) as I am responsible for standard software products at IDS Scheer.

Business intelligence

To develop software tools that allow companies to measure the performance of their business processes is the main topic of my work a IDS Scheer.

Fractal images:

I did a lot of experiments and programming around fractals, especially on Iterated Function Systems. I also implemented a "fractal copying machine" based on the ideas of Hertmut Jürgens, Heinz-Otto Peitgen and Dietmar Saupe and published an article on that topic ("Fraktale - Natur und Fälschung", in German).

Development of electronic devices:

I developed and designed several electronic clocks. The most complex project was a mircoprocessor (6502) based clock with a DCF receiver (to automatically detect the current time) developed during my studies in 1988.

Evolutionary Algorithms and Genetic Programming:

During my PhD I worked on the usage of Evolutionary Algorithms (and more specifially Genetic Programming) for solving optimization problems (read here an introduction in German). I developed "YAGPLIC", an library written in C to analyse theoretical findings as well and demonstrate the power of those principles at several examples. Please have a look at the interactive simulation of the truck-backer-upper problem written in Java. 

Heating control:

I just installed a new wood-based heating from Solvis in at home which is controlled by a  devices that allows logging and analysis of sensors (temparture) and actors of the central heating. Currently im developing some Java based tool to analyze the performance. Click here for details.
