I was a Research Fellow in the
Automated Program Repair
group at NUS, working with Professor
Abhik Roychoudhury.
I defended my PhD in May 2023 at the
School of Computing, NUS,
supervised by Associate Professor
Wei-Ngan Chin.
I received my Master's degree from NUS in 2018 and my Bachelor's degree
from Sun Yat-sen University, China, in 2017.
My research interests are: specification and verification, program analyses,
automated program repair, temporal logic, and separation logic.
