I am an associate professor in the Department of Computer Science and Technology at Tsinghua University. I recieved my Ph.D degree (supvervised by Prof. Jiwu Shu) 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.

本人每年招收博士生 1 人和博士后 1-2 名，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。实验室另有若干博士后/客座研究生名额，感兴趣的同学也可联系我。
