Biography

Julian Cheng received a B. Eng. Degree (First Class) in electrical engineering from the University of Victoria, Victoria, BC, Canada in 1995, a M.Sc. (Eng.) degree in mathematics and engineering from Queen’s University, Kingston, ON, Canada in 1997, and a Ph.D. degree in electrical engineering from the University of Alberta, Edmonton, AB, Canada, in 2003.

In July 2006, He joined the School of Engineering, Faculty of Applied Science, The University of British Columbia (Okanagan campus) as an Assistant Professor. He is now a Full Professor in the same School. Previously, Dr. Cheng worked for Bell-Northern Research (BNR) and Northern Telecom (later known as NORTEL Networks), and taught at both University of Alberta and Lakehead University. His current research interests include digital communications over wireless channels, orthogonal frequency division multiplexing, spread spectrum communications, statistical signal processing for wireless applications, and optical wireless communications. Dr. Cheng co-chaired the 12th Canadian Workshop on Information Theory (CWIT 2011), the 6th EAI International Conference on Game Theory for Networks (GameNet 2016), and the 28th Biennial Symposium on Communications (BSC 2016). In 2012, he chaired the 2012 Wireless Communications, which was held July 3-5, 2012 in Banff, Canada.  In the past, he served as an Area Editor for IEEE Transactions on Communications and severed as an Editor for IEEE Transactions on Communications, IEEE Transactions on Wireless Communications, IEEE Communications Letters,  and IEEE Access. He also served as a Guest Editor for a special issue of IEEE Journal on Selected Areas in Communications on optical wireless communications.

Dr. Cheng was the recipient of numerous scholarships during his undergraduate and graduate studies, which included a President Scholarship from the University of Victoria and a postgraduate scholarship from the Natural Sciences and Engineering Research Council of Canada (NSERC). He was also a winner of the 2002 NSERC Postdoctoral Fellowship competition. In 2021, Dr. Cheng received the Researcher of the Year award (Natural Sciences and Engineering Category), and he was also appointed in 2023 as a Principal’s Research Chair (Tier-1) in Wireless Systems on the UBC Okanagan campus. Dr. Cheng is an elected Fellow of IEEE and AAIA.

In 2021-2022, Dr. Cheng received $1.2 million operational fund from the Department of National Defense (DND) IDEaS program, and his team successfully built the first ultraviolet communication system prototype in Canada. Dr. Cheng continuously holds his NSERC Discovery Grant (DG) and his current DG focuses on Intelligent Wireless Robotics Communications. He is also a two-time recipient of the DND/NSERC DG Supplements Award.

Dr. Cheng served as the Chair of the Electrical Engineering Program in the School of Engineering from July 2019 to December 2021. He was also the founding chair of the IEEE Okanagan Subsection.  He served as the President of the Canadian Society of Information Theory (CSIT) from 2017 to 2021. Currently, he is serving as the Chair of the Radio Communication Committee (RCC) of the IEEE Communications Society.

Dr. Cheng was an Adjunct Professor at University of Alberta (2005-2010), a Visiting Associate Professor at the University of Texas, Dallas (2013-2014), and a Visiting Professor in the Department of Electrical Engineering at Stanford University (2022-2023).
