• The Pinpoint static analysis platform is a major research activity of my group that had both academic and commercial contributions. The core idea is described in Qingkai Shi, Xiao Xiao, Rongxin Wu, Jinguo Zhou, Fan Gang and Charles Zhang Pinpoint: Fast and Precise Sparse Value Flow Analysis for Million Lines of Code. In PLDI 2018: the 39th annual ACM SIGPLAN conference on Programming Language Design and Implementation. Philadelphia, USA, June, 2018. And there is an online demo. Pinpoint was commercialized by Sourcebrella. We have pushed the core techniques forward for type-state bugs(ICSE 2019), extensibility of the core engine(ICSE 2020a), parallelization of static anlaysis (ICSE 2020b), ....

• Casper is the first ever POPL paper from Hong Kong and the idea is both clever and practical. For instance, Rongxin, the first author has applied the idea to solve debugging problems for the WeChat devlopment team. Rongxin Wu, Xiao Xiao, Shing-Chi Cheung, Hongyu Zhang and Charles Zhang. Casper: An Efficient Approach to Call Trace Collection. In POPL 2016: 43rd ACM SIGPLAN-SIGACT Symposium on Principles of Programming Languages, St. Petersburg, Florida, January 2016. (paper)

• This invited paper by JCST summarizes well the core dynamic anlaysis work we did, including LEAP (FSE2010), PECAN(ISSTA 2011), LEAN(OOPSLA 2012), and CLAP(PLDI 2013), for finding errors in multithreaded programs. Jeff Huang and Charles Zhang.Debugging Concurrent Software: Advances and Challenges. In Journal of Computer Science and Technology, Vol. 31 (5): 861-868, 2016 (Invited)

• The CLAP paper is the first ever paper award by PLDI to an Asian university and I am very pround of it. Jeff is now a professor at Texas A&M University. (SIGPLAN PLDI Distinguished Paper Award, Nominated for CACM Research Highlights) Jeff Huang, Charles Zhang and Julian Dolby CLAP: Recording Local Executions to Reproduce Concurrency Failures.
