Kai-Kit Wong received the BEng, the MPhil, and the PhD degrees, all in Electrical and Electronic Engineering, from Hong Kong University of Science and Technology (HKUST), Hong Kong, in 1996, 1998, and 2001, respectively. His PhD research, under the supervision of Professor Ross Murch (Primary Supervisor) and Professor Khaled Ben Letaief (Co-Supervisor), focused on the optimisation of multiuser MIMO antenna systems in the downlink. His paper in WCNC 2000 (Chicago, USA) marked the first ever research work on multiuser MIMO in the field. After graduation, he worked closely with Professor Tung-Sang Ng at the Department of Electrical and Electronic Engineering, University of Hong Kong (HKU) as a Research Assistant Professor, to continue his multiuser MIMO research. From July 2003 to December 2003, he paid a visit to the Wireless Communications Research Department of Lucent Technologies, Bell-Labs, Holmdel, NJ, U.S., to learn and collaborate with Dr. G. J. Foschini and Dr. R. Valenzuela. After that, he spent time in the Smart Antennas Research Group of Stanford University as a Visiting Assistant Professor conducting research on overloaded MIMO detection, under the supervision of Professor Arogyaswami Paulraj. His life in the UK began in December 2004 when he joined the Department of Engineering, University of Hull, to work as a Lecturer. Since August 2006, he has been with University College London (UCL), first at the Adastral Park Campus in Martlesham Heath and then from July 2009 the Department of Electronic and Electrical Engineering in Bloomsbury, where he has become Chair in Wireless Communications (i.e., Chair Professor) since October 2015.

Professor Wong is Fellow of IEEE and Fellow of IET. He is the Subject Editor-in-Chief for IET Electronics Letters - Wireless Communications.
