Xiaoguang “Leo” Liu received his Bachelor’s degree from Chu Kochen Honors College, Zhejiang University, in 2004 and PhD degree from Purdue University, USA, in 2010. He was with the Department of Electrical and Computer Engineering, University of California, Davis, as an assistant professor from 2011 to 2017 and an associate professor from 2017 to 2021. In Mar. 2021, he joined the School of Microelectronics (SME) at the Southern University of Science and Technology (SUSTech), Shenzhen, China, as a full professor.  

At SUSTech, his research group is investigating various aspects of cutting-edge high-frequency and high-speed circuit and system designs. Examples include novel designs and implementation techniques in microelectronic and photonic devices such as micro-electromechanical (MEMS) devices, high-frequency (RF to THz) integrated circuits, high-speed wireline and optical communications, and high-resolution sensing applications using radar, CIS, and laser time-of-flight (ToF) principles. He has published over 140 refereed papers in academic journals and conferences. He has advised and co-advised 18 Ph.D. students and 7 postdoctoral scholars.
