Biography

X.-C. Yuan received his BEng and MEng degrees in optical engineering from Tianjin University, China, in 1985 and 1988, respectively, and his PhD in physics from the University of London, King’s College, in 1994. Between 1994 and 1999, he was a research fellow with the Cavendish Laboratory, the University of Cambridge. He joined the school of EEE of NTU in 1999. His current work deals with diffractive optics and micro-optics including lithography, optical manipulation and imaging at micro- and nano-scale. He has published more than 90 papers on decent journals in optics and photonics. He is a fellow of SPIE – The International Society for Optical Engineering.
