Biography Lian-Kuan Chen received the B.S. degree in electrical engineering from National Taiwan University in 1983 and the M.S. and Ph.D. degree in electrical engineering from Columbia University, New York, in 1992. He joined the faculty of Department of Information Engineering, the Chinese University of Hong Kong and established the Lightwave Communications Laboratory in1992. He was the Department Chairman in 2004-2006. In 2007-2013, he was a member of the engineering panel of Hong Kong Government Research Grant Council. He served as the director for the Centre for Advanced Research in Photonics in 2010-2015. His research includes visible light communication, optical wireless communication, next-generation local access networks, transmission systems, optical/electronic signal processing, performance monitoring, and bio-photonics. Professor Chen has published more than 270 papers in referred international conferences and journals. He is a senior member of IEEE Photonics Society and Communications Society, and a member of OSA.? He has served as an associate editor of IEEE Photonics Technology Letters (2005-2011) and OSA/IEEE Journal of Optical Communications and Networking (2012-2015).? For his name's sake (in Chinese), he believes he will continue to engage in research related to Light in the foreseeable future.
