About Me

Dr. Guanghui ZHANG obtained his PhD degree from the Department of Information Engineering of The Chinese University of Hong Kong in 2020, and worked as a postdoctoral researcher at The Chinese University of Hong Kong from 2020 to 2021, and as a research assistant professor at the Department of Computer Science of The Hong Kong Baptist University from 2021 to 2022. His research broadly lies in applying state-of-the-art machine learning techniques to video streaming systems to drastically improve the viewer-watching experience (i.e., Quality-of-Experience).
