I am an associate professor in the Department of Computer Science and Technology at Tsinghua University. I recieved my Ph.D degree from Tsinghua University in 2015, and Bachelor degree from Nanjing University in 2009. My research interest is in the area of computer systems and architecture, with an emphasis on memory, storage and file systems.

本人招收博士生 2 人、博士后 1-2 名、工程师 1 人、实习生若干人,欢迎对计算机存储系统(操作系统、内存与存储系统、分布式系统以及新型体系结构等) 感兴趣的同学与我联系。

Several Ph.D and Postdoc positions are available. If you are interested in computer system or computer architecture, please contact me.
