(Physical Measurement Laboratory, 1970-1999)
For his exemplary contributions to improved dissemination of the nation's electrical units, and the development and promotion of an internationally accepted system to assure the traceability of measurement results nationwide to the SI.
(Engineering Laboratory, 1983-2016)
For advancing understanding of how and why structures fail — using disaster investigations, developing novel laboratory tools and facilities, and leading standards improvements to make buildings and other structures safer.
(Information Technology Laboratory, 1969-2019)
For outstanding technical contributions and exceptional leadership to provide an online, interactive, and authoritative reference for special functions of applied mathematics, the NIST Digital Library of Mathematical Functions.
(Physical Measurement Laboratory, 1996-2016)
For revolutionizing absolute radiometric calibration methods and increasing the accuracy of measurements relevant to long-term global climate change and daily weather forecasting.
(Physical Measurement Laboratory, 1972-2019)
For creatively advancing standards for measuring thermophysical properties of fluids and for best-in-the-world measurements of fluid properties, fluid flow, thermodynamic temperature, and the Boltzmann constant resulting in worldwide scientific impact.
(Director’s Office, 1993-2008 and 2011-2017)
For exceptional leadership on standards policy development and implementation at the highest levels of government and the private-sector-led standards community and as NIST’s Chief Operating Officer.
