I am currently a third-year Ph.D. candidate at Hong Kong University of Science and Technology(香港科技大学) in CASTLE Lab, supervised by Prof. Shing-Chi Cheung(張成志) and Prof. Shuai Wang(王帅).

Before that, I obtained my Bechelor’s Degree at Harbin Institute of Technology, Shenzhen(哈尔滨工业大学（深圳）), advised by Prof. Cuiyun Gao(高翠芸) of Software Analysitics and Reliability Lab.

My current research interest is on SOFTWARE ENGINEERING FOR ARTIFICIAL INTELLIGENCE (SE FOR AI), TESTING CODING AGENT, and CAUSALITY-BASED ANALYSIS.
