Assistant Professor School of Microelectronics   Research Group

Dr. Kwai Hei Li received the B.Eng. and Ph.D. degrees in Electrical and Electronic Engineering from the University of Hong Kong in 2009 and 2013, respectively. After graduation, he received 1-year postdoctoral research training at the McGill University in Canada. He worked as a Research Assistant Professor in the Department of Electrical and Electronic Engineering at HKU from 2016 to 2019. He is now an Assistant Professor at the Southern University of Science and Technology. He has published more than 80 papers in international academic journals and conferences, 1 book and 2 book chapters, and 2 U.S. patent applications. Research results were highlighted in industry magazines such as Compound Semiconductor and Semiconductor Today. He served as local arrangement chair and finance chair of the 2016 and 2020 IEEE International Conference on Electronic Devices and Solid State Circuits respectively. Dr. Li has been PI of several research projects, including General Research Funds (GRF) sponsored by the Research Grants Council (RGC) of Hong Kong
