Fortran77/Python. Simulating the impact of three-dimensional turbulence on the formation rates of aerosol particles. The very clever method of this simulation reduces the three-dimensional problem to a simple one-dimensional one reducing the calculation time by some powers of ten. 

Python: Dispatching the calculation time on all available Silicon Graphics, IBM, SUN Server und PCs in the institute to get finished with the simulation in my life span.

Delphi: Development of a fitting software to parametrize the 6-dimensional result set of time series as a simple coefficient matrix of a function with 4 parameters, with an accuracy of the time series of 95% in average.

2002 Stratos AG, Zwenkau

Position ended. Need money to write my dissertation.

Senior Software-Developer. Delphi: Software for the management of travel expenses. Delphi/Python: Embedded Python interpreter to create a small interpreter language for the description and the rendering of printed forms. Thus eliminating the burden to compile a new executable if a customer needs a single letter changed in a  form.

2003 University of Leizig PhD thesis  "Der Einfluß turbulenter Mischungsprozesse auf die Bildungsraten atmosphärischer Aerosolpartikel"
2004 Leipzig Launch of Inqbus IT-Consulting, CEO to the day
2005 Leipzig Launch of Inqbus Hosting GbR (zusammen mit Maik Derstappen), CEO to the day
2011 Leipzig Formation of Inqbus GmbH & Co KG. Four striking software companies from Leipzig melt together

Renaming "Inqbus IT-consulting" to "Inqbus Scientific Computing".

The initial name does no longer match the focus. Ten years ago I did consulting, but currently inqbus is producing high-quality software mainly for scientific purposes. Consulting was never much fun - I like to program and dig deep into problems - that's fun.

 

Together with my wife Ina (also PhD in Meteorology) and our daughter Elfi I life in south Bavaria near the alps. Munich is 100 kilometers away and the famous castle of Neuschwanstein lies 30 kilometers to the south. We have a large garden populated by our three cats, maintained mostly by Ina.

In my spare time, I work as the speaker for a small but very active group of photographers.
