About Me

I am a final year PhD student in the Department of Computer Science and Technology at Tsinghua University. Before that, I received my Bachelor’s degree from Honors College (formerly known as School of Advanced Engineering), Beihang University. My advisors are Jiwu Shu and Youyou Lu. During 2019 - 2020, I worked as a visiting scholar at ADSL, UW-Madison, advised by 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, ICDE, ASPLOS, VLDB, Eurosys, DAC, USENIX ATC, ToS, TC, etc.
