Biography

I work at SystemsResearch@Google (SRG). My research interests include operating systems, storage, and distributed systems.

I received my Ph.D. from the University of Wisconsin-Madison (2022), where I worked with awesome Andrea Arpaci-Dusseau and Remzi Arpaci-Dusseau. I also received my master’s degree from UW-Madison (2020). I received my B.E. from University of Science and Technology of China (USTC, 2016).

Research

I have a broad interest in systems. My recent research aims to improve memory efficiency of hyperscalers and flatten their memory costs. It extends my PhD work on building systems for emerging storage architecture (tiering and disaggregation) and devices (Flash and Optane).

Key Words: Memory Management, Caching/Tiering, Multi-tenancy, Data-intensive Applications.
