Hanzhi Liu (刘瀚之)

Ph.D. candidate, Nanjing University

I'm a fourth-year Ph.D. candidate in SPAR Group of Institute of Computer Software, Nanjing University, supervised by Assoc. Prof. Yanyan Jiang and Prof. Chang Xu. Currently my research focuses on understanding and debugging operating system kernels and other system software. I'm also interested in system reliability and observability, as well as designing systems that can solve critical real-world problems.
