Young Jong Lee

Research Chemist, Project Leader

Since Young Jong Lee joined NIST in 2006, he has been developing new hyperspectral imaging and spectroscopy technologies based on coherent Raman and infrared (IR) absorption to measure the quantitative and structural information of complex materials and biological systems. His research has been extended to development of new spectroscopic methods for non-invasive, high-sensitivity characterization of higher-order structures of protein and polymers.
