I’m a first year PhD. student in the Computer Science Department of Carnegie Mellon University and a member of Catalyst Group. I’m fortunately to be advised by Zhihao Jia. Before this, I received my Master degree from Carnegie Mellon University, advised by Zhihao Jia. Before CMU, I received my B.S. degree from Dalian University of Technology.

I am interested in building efficient and scalable systems for machine learning applications.
