I am a fourth-year PhD student at University of Maryland, College Park, fortunate to be advised by Prof. Alan (Zaoxing) Liu. My research interests are broadly in systems and networking. In particular, I attempt to bridge the gap between approximate algorithms (e.g., sampling, sketches) and practical computing systems (e.g., graph systems, key-value store migration systems), aiming to improve query performance and system scalability. Currently, I’m working on scalable performance monitoring systems.

I received my B.E. for Computer Science from Xi’an Jiaotong University in 2021.
