I am currently leading the program analysis research group at the Institute of Computing Technology, Chinese Academy of Sciences. Our focus is on developing program analysis techniques and tools to enhance software reliability and security. One of our notable accomplishments is the commercial tool Wukong, which detects deep software errors involving complex inter-procedural dependences. Wukong has successfully identified numerous errors and potential vulnerabilities in popular open-source applications, with over 200 bugs confirmed by original developers and more than 20 assigned CVEs. Our research has been published in top conferences such as SOSP, CCS, USENIX SECURITY, FSE, ASE, and CGO. We have received the ASE distinguished paper award and the CCS best paper honorable mention in 2019 and 2022, respectively.
