About
I have worked in dimensional metrology, geometrical dimensioning and tolerancing, and quality systems for calibration laboratories since receiving my M.Sc. from the Technical University of Denmark in 1984. I received my Ph.D. in 1987 (diploma dated 1988) and worked as a metrology consultant at the Institute for Product Development in Denmark until 1991.
In 1991, I moved to the United States and joined Cummins Engine Co. as Technical Manager – Corporate Standards, a position I held until 1998. Since 1998, I have been President of HN Metrology Consulting, Inc.
