THREE Faculty members from the Department of Electrical & Computer Engineering are elevated to IEEE Fellows on 1 January. They are Professor Lim Teng Joon, Associate Professor Zhang Rui, and Associate Professor Yan Shuicheng.
IEEE Fellow is a distinction reserved for select IEEE members, whose extraordinary achievements in any of the IEEE’s field of interest are deemed fitting for this prestigious grade elevation.
Prof Lim Teng Joon, who is currently NUS Engineering’s Vice Dean (Graduate Programmes), has made significant contributions to research on wireless communications, including the Internet of Things, heterogeneous networks, cooperative transmission, energy-optimised communication networks, multicarrier modulation, MIMO, cooperative diversity, cognitive radio, and stochastic geometry for wireless networks.
Prof Lim’s work on multi-user detection in CDMA is well known, as well as his recent work on relay networks, cognitive radio, multi-carrier phase noise estimation, and energy harvesting communication systems. The impact of his work is evident, based on more than 5,000 citations to his publications, and their influence on wireless technology development.
Assoc Prof Zhang Rui is elevated to IEEE Fellow in recognition of his contributions to cognitive radio and energy harvesting communications, which are revolutionary and transforming technologies that have the potential of resolving the spectrum and energy shortage in wireless communications. In cognitive radio, the most critical challenge is to enable secondary or unlicensed users to transmit concurrently with primary or licensed users with no harmful interference to them.
Assoc Prof Zhang is one of the innovators who first proposed and rigorously studied the technique of “interference temperature” and “cognitive beamforming” to efficiently control the interference in spectrum sharing.
Energy harvesting is a green and cost-effective solution to provide energy for wireless devices. Compared to traditional environmental energy harvesting which is intermittent and random, wireless power transfer with dedicated transmitters is controllable and more reliable. Assoc Prof Zhang pioneered the application of wireless power transfer in wireless communications, and the first to optimise the design of multi-antenna “energy beamforming” for directional power transmission to significantly enhance the efficiency of wireless power transfer over long distance.
Furthermore, he is the first to characterise the fundamental rate-energy tradeoffs in simultaneous wireless information and power transfer (SWIPT), which has resulted in a new research area in wireless communications. Assoc Prof Zhang is listed in the latest Highly Cited Researchers 2016 report published by Clarivate Analytics, formerly the Intellectual Property & Science business of Thomas Reuters.
Assoc Prof Yan Shuicheng is also the founding leader of the Learning and Vision Research Group (http://www.lv-nus.org). His research areas include machine learning, computer vision and multimedia.
Assoc Prof Yan has authored/co-authored hundreds of technical papers over a wide range of research topics, with Google Scholar citation over 20,000 times and H‐index 66. His team has won several PASCAL VOC and ILSVRC competitions, as well as received the best (student) paper prizes for more than ten times. Assoc Prof Yan has been listed in the Highly Cited Researchers report since 2014.
