From November 2009 until October 2011 I stayed as PostDoc Researcher at the Honiden Laboratory at the National Institute of Informatics. My supervisor during this time was Prof. Shinichi Honiden.
My work at NII
During these two years I conducted my research under two major headlines:
- Multi-Agent Planning for Self-Optimizing Manufacturing Systems
- Advanced Decision Making for Flexible and Adaptive Software Systems
Having graduated in Business Information Systems and done my Ph.D. in a research project devoted to mechanical and control engineering, the new environment provided my colleagues with experience in several facets of software engineering, what widened my scope of both the methods I use as well as application examples.
Besides collaboration with partners from the Honiden Lab, the international environment at the NII also enabled me to establish research cooperation with institutions outside of Japan. Very valuable was the possibility to invite master and Ph.D. students from partner organizations all over the world to participate in and of course to help me with my research. During the two years, 5 intern students from Europe, Asia and South America worked on my research topics, each one staying for between three and six month. Several research papers are the result of the collaboration with these highly motivated students.
Since I am working on the applied side of computer science, extensive experimental validation is an important part of my research. The NII and the Honiden Laboratory provided me with an excellent infrastructure to execute my experiments.

Everyday life in Tokyo
Before I came to Japan I tried - of course - to learn some Japanese. Before applying for the scholar ship I had no special relationship to Japan and thus started from the scratch after receiving the acceptance letter. However, the last two weeks before I left Germany I was very busy and didn't manage to do anything for my Japanese. So, when I finally arrived I didn't understand anything and couldn't speak the simplest sentences. I was very surprised how easy everydays life was organized with almost no Japanese. Some examples:
- I rented my flat before I came over the internet at a home agency with English speaking stuff and good support. Since I did a very lucky pick with my flat, a never had to relocate although I could cancel the contract on monthly basis.
- Shopping in Supermarkets or Convenience Stores is easily done without talking the language of the shop clerks.
- Opening a bank account was easily managed without common language with the lady at the counter.
I commuted about 40 minutes from the door of my flat in Sangenjaya to the NII. All signs in the station and trains of the several railway companies in Tokyo are bilingual. And yes, during rush-hours the train are very full. But only on my first day I was actually pressed by station employee into the train.
However, a two years stay in a foreign country is of course much more pleasant if you can speak the language a little bit. NII supports the learning of the Japanese language. During my stay, two different types of Japanese courses were offered. Futhermore, the NII library offers various learning materials, from which I found the "Pimsleur" audio progam extremely useful.
