About Me

I am currently a second year Ph.D. student in the Department of Compute Science at City University of Hong Kong, advised by Prof. Chun Jason Xue. Before coming to CityU, I received my B.Eng. degree in Computer Science and Technology in 2013 and M.Sc. degree in High Reliability Embedded System in 2017 from Capital Normal University.

Research Interests

My research interests are in building reliable and high performance non-volatile memory systems. My current research focuses on designing efficient transactions for persistent memories.
