About Me

I am a PhD candidate at School of Computing, National University of Singapore, advised by Dr. Jialin Li. My research interests are in distributed systems and operating systems, with a focus on datacenter infrastructure. I also work with Dr. Antoine Kaufmann on full-system simulation.

Before starting PhD, I received my master’s degree from National University of Singapore. I obtained my bachalor’s degree at Beihang University, where I worked on operating system projects with Dr. Lei Wang.
