Two students whose research aims to improve lighting technologies and reduce energy consumption have won a top international prize. Guangyu Liu and Jing Zhang, Ph.D. candidates in electrical engineering at Lehigh, will receive the 2012 Scholarship in Optics and Photonics from the International Society for Optics and Photonics (SPIE). Together with 138 other students from around the world, they will accept their awards next February in San Francisco at Photonics West 2013, SPIE's annual conference. Liu and Zhang both earned bachelor's degrees from Huazhong University of Science and Technology in Wuhan, China. Since enrolling at Lehigh, each has published more than 40 articles in journals and conference proceedings. Both are advised by Nelson Tansu, the Class of 1961 Associate Professor of Electrical and Computer Engineering.
