For lowering trade barriers for metered liquids such as petroleum and milk by leading the development of international standards for liquid and gas flow meters.
For operation, maintenance, and sustained support of the Synchrotron Ultraviolet Radiation Facility (SURF III) as the primary national ultraviolet radiation standard for critical space programs.
For pioneering contributions in neutron imaging, including the development of a highly sensitive neutron phase imaging technique and the demonstration of the world's first practical neutron microscope.
For restoration and recalibration of the NIST 4.45 meganewton (1 million pounds-force) force standard that serves as the world's largest primary force standard.
For demonstrating a novel all-magnetic alternative to medical imaging through developing a class of nanoscale radio-frequency probes for diagnostics and treatment.
For developing and perfecting optical lattice atomic clocks as the most stable and accurate clocks in the world, which will have future impacts on advanced communications and a broad range of precision measurements far beyond timekeeping.
