Department of Computer Science

University of Southern California

I am a Ph.D. student at CS department of USC. I work with Prof. Aiichiro Nakano in Collaborartory for Advanced Computing and Simulations (CACS).

Before joining USC, I received B.S. in computer science from Huazhong University of Science and Technology, China and M.S. in computer science from Graduate University of Chinese Academy of Sciences, China.

My ambition is to become a world class researcher in computer science, conducting state-of-art research to push back the frontiers of computer science.

My major research interest lies in high-performance parallel computing, parallel algorithms and their implementation, scientific simulations and innovative computer architectures.
