About

I am a Ph.D. candidate in the Computer Science Department at the Univercity of California, Irvine (UCI), supervised by Prof. Qi Alfred Chen. I am also working closely with Prof. Joshua Garcia.

My primary research focus lies in the field of software testing and security analysis for cyber-physical systems. Through my work, I strive to identify distinct patterns and potential risks associated with bugs and vulnerabilities in these systems. My ultimate objective is to develop automated tools that assist developers in building secure and reliable software.

I earned my B.Sc. degree in Computer Science from Nanjing University before joining UCI.
