Biography
I am a second-year Ph.D. Student at the Department of Computer Science and Engineering, the Chinese University of Hong Kong (CUHK),
under the supervision of Prof. Bei YU and Prof. Martin D.F. Wong since Fall 2022. Prior to that, I obtained my B.Eng. and M.S. degree from Fudan University under the supervision of Prof. Lingli Wang in 2015-2022.
My research interest is to solve critical problems in electronic design automation (EDA) with advanced artificial intelligence (AI) methods. Besides research, I love playing the piano and listening to classical music in my spare time.
