708 Computer Science Building zqzuo AT nju.edu.cn 163 Xianlin Road, Qixia District, Nanjing, China
About Me
I am now an associate professor in the School of Computer Science & Technology, Nanjing University, China.
Before joining NJU, I got my PhD from National University of Singapore in 2015, and worked as a postdoc scholar at University of California, Irvine from 2015 to 2017.
I am recruiting PhD, Master and Undergraduate students. If interested, please feel free to drop me an email.
现招收博士、硕士以及南京大学本科生，对系统软件、编译器与运行时感兴趣的同学，请通过邮件（附简历和成绩单）取得联系。
I am serving the PC for the following conferences. Please consider submitting your work to them.
My research interests span Programming Languages, Software Engineering, and Systems.
I have been recently focusing on building and customizing systems software (e.g., compilers, runtime environments, and operating systems) for program efficiency, reliability, and safety.
