Wei Liu received his BSc (Space Physics) and LLB. degrees from Peking University, China, in 1996 and 1997, respectively, MPhil from the Department of Electrical and Electronic Engineering, University of Hong Kong in 2001, and PhD from the School of Electronics and Computer Science, University of Southampton, UK, in 2003. He then worked as a postdoc first at Southampton and later at Imperial College London. In September 2005, he joined the Department of Electronic and Electrical Engineering, University of Sheffield, UK, first as a Lecturer and then a Senior Lecturer. Since September 2023, he has been a Reader at the School of Electronic Engineering and Computer Science, Queen Mary University of London, UK. He has published 400+ journal and conference papers, five book chapters, and two research monographs titled "Wideband Beamforming: Concepts and Techniques'' (Wiley, March 2010) and "Low-Cost Smart Antennas'' (Wiley, March 2019), respectively. His research interests cover a wide range of topics in signal processing, with a focus on sensor array signal processing and its various applications, such as robotics and autonomous systems, human computer interface, radar, sonar, and wireless communications.

He is a member of the Digital Signal Processing Technical Committee of the IEEE Circuits and Systems Society (Chair for 2022-2024), the Sensor Array and Multichannel Signal Processing Technical Committee of the IEEE Signal Processing Society (SPS) (Chair for 2021-2022), the IEEE SPS Technical Directions Board (2021-2022), and the IEEE SPS Conference Board (2022-2023). He also acted as an associate editor for IEEE Trans. on Signal Processing, IEEE Access, and Journal of the Franklin Institute, and currently he is an associate editor for IEEE Antennas and Wireless Propagation Letters, and an Executive Associate Editor-in-Chief of the Frontiers of Information Technology and Electronic Engineering. He is an IEEE Distinguished Lecturer for the Aerospace and Electronic Systems Society (2023-2024).
