I studied technical chemistry. After that I worked for 3 years at a shipyard, 2 years in dairy research and 3 years in the plastics industry.
The following 32 years I was a scientific employee at the Hamburg University of Applied Sciences (Germany): 14 years in the process engineering laboratory and 18 years in the ergonomics laboratory. I taught the students how to do the laboratory experiments, always trying out new ideas in order to optimize my teaching style. In the final years I also gave lectures. Since August 2021 I am retired.
