About Me

On this page you find some personal information about my (mainly technical and scientific) background. If you are interested in the professional consultancy services I offer please refer to the Services page. If you are interested in a full CV please contact me.

I was born in Cologne, district Kalk, in 1975. When I was about four years old my parents decided to move to a small town close by called Haan. In early years I discovered my fascination for computers. It all started with the gaming console Philips Videopac G7000. A few years later I was the proud owner of my first programmable computer, a Phillips MSX VG-8000.

These days it seems bizarre that I spent hours and hours of typing in sourcecode listings published in magazines like the MSX Revue. And I could not even save the files since I had no tape or disk…

Next the legendary Commodore 64. After all these endless hours in the dungeons of Skara Brae I upgraded to an Amiga 2000 where I did more extensive programming steps in AmigaBASIC and Assembler. Another passion was composing music with tools like Protracker. One of my greatest purchases was a ZyXEL 14400 bps modem for around 1000 DM. Proudly I could connect to the BBSs of the world. And pay a fortune for the connection fee…

After school I moved in 1995 to Berlin to study Informatics at the Technical University. I bought a regular PC and started discovering the Internet. I was fascinated by the Solaris operating system which we used at the university. Therefore I started playing with Linux on my PC, which is still my favourite operating system. Becoming a research and teaching assistant at the group of Hartmut Ehrig aroused my interest for theoretical computer science, which became my main study topic. So it was a natural step to continue with a Ph.D. after my diploma was done.

I moved to the Radboud University in Nijmegen. My supervisor was, and still is, Jan Tretmans. My research topic became formal model-based testing. Currently I am in the process of writing down the last parts of my thesis. In between my Nijmegen time I went for 18 months as a guest researcher to the Italian National Research Council (CNR) in Pisa, Italy; group of Antonia Bertolino.

By this time I am back in Cologne. I am now professionally working with the fascinating topic of model-based testing, being a freelancer in the domain. I could not imagine a topic better suited to combine ambitious research with practical challenges.

There are many interesting projects I am currently involved in, like the Model-Based Testing Community.
