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.

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