Kevin O Douglass (Fed)

Kevin Douglass is a world class molecular spectroscopist in the Physical Measurement Laboratory at NIST. He is developing rapid and sensitive spectroscopic techniques for the measurement of dynamic pressure.  The goal is to develop the first dynamic pressure standard for the United States based on the fundamentals of spectroscopy. Kevin came to NIST in 2007 and has been developing state-of-the-art spectroscopic tools in areas spanning from the microwave, terahertz, near infrared, and the ultraviolet. His research thus far has resulted in 2 patents with a third pending. Kevin's current research also extends into the nano-fabricated photonic device technology and leveraging this rapidly evolving technology to develop novel ultra-compact, low cost spectroscopic sensors.
