received a BSc degree in Radio Physics from Nanjing University, Nanjing, China and a Ph.D degree from University of Birmingham, Birmingham, U.K. His doctoral research concerned high-temperature superconductor microwave filters. He was with the National Satellite Meteorological Centre of China, Beijing, China. After completing his PhD, he was with the University of Birmingham, where his research concerned phased arrays for reflector observing systems. Then he moved tothe Department of Electronic and Electrical Engineering, University of Bristol, Bristol, U.K. His research in Bristol was mainly on the development of highly efficient and linear amplifiers. He is with the Department of Electrical Engineering and Electronics, University of Liverpool, Liverpool, UK since 2013. His past and current research interests include microwave power amplifiers, filters, electromagnetic compatibility, frequency selective surfaces, energy harvesting and wireless power transfer.
