I am a postdoctoral researcher in the Advanced Software Technologies (AST) lab at ETH Zurich, mentored by Prof. Zhendong Su. I obtained my Ph.D. in Computer Science and Engineering from The Hong Kong University of Science and Technology (HKUST) in 2024 under the supervision of Prof. Shuai Wang. Prior to that, I received my B.S. in Computer Science from Fudan University in 2020.
