LIU Yanjun
Associate Professor

Dr. Yanjun Liu is currently an associate professor at Southern University of Science and Technology (SUSTech), China. He received his Ph.D. degree in photonics from Nanyang Technological University, Singapore, in 2007, M.S. degree in optics from Fudan University, China, in 2003, and B.E. degree in optoelectronics from Shandong University, China, in 2000. Before joining SUSTech, he was a research scientist in ASTAR, Singapore (2010-2016), and postdoctoral scholar in Penn State University (2008-2010) and European Laboratory for Non-Linear Spectroscopy (LENS) (2007-2008). His research interests include liquid crystal photonics, active plasmonics and metamaterials, etc. He is experienced in polymer micro/nano-photonic structures, liquid crystal devices, and laser holograms. He has authored/co-authored over 100 peer-reviewed journal publications and over 30 peer-reviewed conference papers in his research fields. He is the recipient of Chinese government award for outstanding self-financed students abroad, ICTP TRIL programme fellowship in Italy, and the 12th thousand young talents plan.
