I am an Assistant Researcher/Postdoc in the Department of Computer Science and Technology at Tsinghua University. Before that, 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.

Postdoc positions are available in our group (Storage@THU). If you are interested in storage systems, please email me or Prof. Jiwu Shu. Our group has broad interests in storage research, including both architecture and system levels. Currently, we are focusing on non-volatile memory based storage systems, big data storage systems, and storage reliability.
