Assistant Professor School of Microelectronics

Dr. Yuan GAO received the B.Eng. and M.Eng. degrees from Xi'an Jiaotong University in 2009 and 2012, respectively, and the Ph.D. degree from the Hong Kong University of Science and Technology (HKUST) in 2017. From 2017 to 2019, he was a Post-Doctoral Fellow with HKUST. Since November 2019, he serves as an Assistant Professor at the School of Microelectronics, Southern University of Science and Technology. His research interests include analog and power integrated circuits design, especially for various high-voltage applications. Dr. Gao has published more than 20 international journals and conferences, including 4 JSSC (top1 journal in IC design) and 1 ISSCC (top1 conference in IC design, also known as ‘Chip Olympics’). He also serves on the review boards of multiple international journals and conferences.
