About me

I am a final-year Ph.D. student in Computer Science at The Hong Kong University of Science and Technology (HKUST), advised by Prof. Shuai Wang. Currently, I'm visiting the Advanced Software Technologies (AST) Lab at ETH Zurich (ETH), advised by Prof. Zhendong Su. Prior to my Ph.D. studies, I obtained my B.S. in Computer Science from Harbin Institute of Technology, Shenzhen. I also participated in The Cornell, Maryland, Max Planck Pre-doctoral Research School.
