Catherine Cooksey

Catherine Cooksey is a research chemist in the Sensor Science Division at the National Institute of Standards and Technology. She is responsible for maintaining the national scale for transmittance as well as conducting and managing transmittance calibrations. Catherine’s research activities include advancing transmittance and reflectance measurement methods and the application of those methods to various measurement challenges.

In 2018, she received a NIST Bronze Medal Award for establishing an accurate database of human skin reflectance measurements for wavelengths ranging from the shortwave infrared to the ultraviolet spectral region and a Judson C. French Award for vastly improving the NIST reflectance measurement services. Additionally, Catherine serves as division quality manager.
