I am an Assistant Professor in the Department of Computer Science and Technology at Tsinghua University. Before that, I worked as a postdoc researcher (assistant researcher) at Tsinghua. 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 storage and file systems, with an emphasis on non-volatile memories and file systems.

本人招收免试推荐直博生/博士后，欢迎对计算机存储系统（文件系统、存储系统、分布式系统、新型存储体系结构、大数据存储等）感兴趣的同学与我联系。实验室另有若干直博生/博士后/客座研究生名额，感兴趣的同学也可联系我。
Several Ph.D and Postdoc positions are available. If you are interested in computer system or computer architecture, please contact me.
