Henrik S. Nielsen
The following information is intended to give a general impression of my experience in the fields of dimensional metrology, geometrical dimensioning and tolerancing and quality systems for calibration laboratories.
I have been working in these fields since I received my masters degree in 1984. I finished my Ph. D. in 1987 and then worked as a metrology consultant until 1991.
In 1991 I moved to the US. I worked for Cummins Engine Co. as Technical Manager - Corporate Standards from 1991 to 1998.
I have worked as an independent consultant since 1998.
