Biography

I am a system research engineer 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’m broadly interested in systems. Recently, I built systems for new storage devices (such as Flash and PMEM) and new storage architecture (such as tiering and disaggregated storage/memory). I worked on topics such as caching, multi-tenancy, databases.
