Research Strengths

At present, the Department has four research groups: Communications Research Group, Multimedia Signal Processing Research Group, Nonlinear Circuits and Systems Research Group, and Photonic Systems and Devices Research Group. These research groups are led by internationally renowned professors who are Fellows of IEEE or Royal Academy of Engineering.

Besides serving/having served as associate editors of reputable international journals, our colleagues are/were editors-in-chief of IEEE journals such as IEEE Transactions of Circuits and Systems II, IEEE Circuits and Systems Magazine, IEEE Circuits and Systems Newsletter; Vice-President of the IEEE Signal Processing Society, President-Elect of the Asia Pacific Signal and Information Association, and Chang Jiang Scholars Chair Professor. They are also serving / have served as the General / Technical Program Chairmen of some of the largest and most reputable international conferences such as IEEE International Conference on Image Processing, IEEE International Conference on Multimedia & Expo, International Conference on Digital Signal Processing, Optoelectronics and Communications Conference. Our colleagues are frequently invited to give keynotes / plenary talks in IEEE international conferences and workshops. Recently, our professors have been the co-investigators of two theme-based research projects and have received a total funding of over $18M from the Research Grants Council. The Department has further received more than $15M research funding from Huawei Technologies Co. Ltd.
