Dana R. Defibaugh

Dana Defibaugh has been a member of the Infrared Technology Group in the Sensor Science Division of NIST since 2012. Presently his focused effort involves support and development in the Low-Background Infrared (LBIR) facility for absolute detector-based irradiance and radiance calibrations in climate monitoring technology. During this time, Dana has been responsible for the implementation of the Thermal-infrared Transfer Radiometer (TXR); a portable radiometer for transferring NIST radiometric scales to other calibration facilities.

In NIST work prior to joining the Infrared Technology Group, Dana was involved in realizing, maintaining, and disseminating the national measurement standards for vacuum and low gas flow through calibration-related services, international comparisons, and fundamental and applied research. Also, Mr. Defibaugh has spent several years measuring the thermophysical properties of replacements for ozone-layer-damaging refrigerants through Equation of State, compressed liquid density, and vapor pressure measurements. Dana has co-authored 25+ papers on these subjects.

When not at NIST Dana enjoys the art and science of hop, malt, and yeast chemistry, automotive restoration, and service dog raising/training.
