Dr. Liyong Ren is from Shaanxi province, China. He got his S.B. degree in Optoelectronics from the Department of Physics in Northwest University in 1995. Since then he was selected as a college teacher by that university and became a lecturer in 2000. Also at that university he obtained his S.M. degree in Optics in 2000. From March 2001 to February 2004, he pursued his doctorate degree in Shanghai Institute of Optics and Fine Mechanics (SIOM), Chinese Academy of Sciences (CAS), and earned a Ph. D degree in March 2004. After that he joined the State Key Laboratory of Transient Optics and Photonics, Xi'an Institute of Optics and Precision Mechanics (XIOPM), CAS, as an associate professor. He was awarded a JSPS (Japan Society for the Promotion of Science) postdoctoral fellowship for foreign researchers to conduct a collaborating research in the University of Electro-Communications from May 2007 to April 2009. From 2009, he become a professor at XIOPM. He is the OSA Senior Member, the SPIE Senior Member and the member of COS (Chinese Optical Society). His current research interests include fiber nonlinear optics, fiber sensing technology, slow-light technology, microstructured optics and information photonics.
