Eric S. Stanfield (Fed)

Sr. Dimensional Metrologist

Mr. Stanfield is a dimensional metrologist and mechanical engineer in the Dimensional Metrology Group in the Sensor Science Division of the Physical Measurement Laboratory (PML) at the National Institute of Standards and Technology (NIST).

In his current position, he is responsible for the realization and dissemination of the SI unit of length through the provision of measurement services to U.S. industry, academia, and other government agencies. His expertise includes advanced mechanical and interferometric dimensional measurement, self-calibrating techniques, coordinate metrology, uncertainty determination, and ISO/IEC 17025 quality system requirements. He actively manages and leads measurement science research efforts to improve the accuracy and efficiency of current services and the development of new methods to address measurement needs in support of advanced manufacturing.
