About Me

I am currently an Assistant Lecturer in the Department of Computer Science and Engineering at The Chinese University of Hong Kong. At the same time, I am a Ph.D. candidate under the guidance of Professor W.-K. Ma. In 2020 and 2018, I completed my M. Phil. and B. Eng. degrees, respectively. My research interests include signal processing, optimization, and machine learning for communications. My teaching interest lies in EECS subjects, general education for AI, and foundation mathematics. Also, I have been offering foundation service courses in computer literacy. Prior to joining CUHK, I was an Assistant Lecturer in HKU SPACE Community College, wherein I served as the programme coordinator of Associate of Engineering (2022) and Higher Diploma of Geotechnical Engineering (2021).
