About Me

I am a Postdoctoral Researcher with the Department of Computer Science and Technology, Tsinghua University. I obtained my Ph.D. degree from Tsinghua University (advised by Jiwu Shu and Youyou Lu), and Bachelor degree from Honors College (formerly known as School of Advanced Engineering), Beihang University. During 2019 - 2020, I worked as a visiting scholar at ADSL, UW-Madison, advised by Prof. Remzi Arpaci-Dusseau, Andrea Arpaci-Dusseau, and Xiangyao Yu.

My research area mainly covers distributed systems and storage systems. I’m particularly interested in building storage systems on emerging hardware (e.g., Non-Volatile Memory, RDMA). Recently, I am paying close attention to the “Killer Microseconds” problem. My work has been published on FAST, ASPLOS, Eurosys, USENIX ATC, SIGMOD, VLDB, etc.
