Xianghuai (William) Wang received his PhD in Physical Chemistry from University of Science and Technology of China for the study of the high-resolution and high sensitivity infrared molecular spectroscopy. He then held Post-Doctoral positions at Northwestern University, UCLA and Bowling Green State University, using various spectroscopic method (IR, NIR, Raman, fluorescence, transient state UV-Vis, etc.) to study different materials. He stared his career in industry with Dow Corning, focusing on IR/Raman/NIR spectroscopy study on silicone and silane material. Currently, he is a Principal Research Scientist within the Measurement Science department at Lubrizol. His research interest is to apply in situ monitoring spectroscopic technique in process control from small lab scale to manufacture scale. He has published 40 peer-reviewed articles and submitted 6 patent applications.
