About Me

I am a Ph.D. candidate in the School of ECE at Georgia Tech, where I work in the HPArch lab under the advisement of Prof. Hyesoon Kim. My research interests are in the areas of computer architecture and computer system, including large-scale graph computing system and architecture, near-data processing, and emerging memory technologies. I received my M.S. and B.S. degrees in Electronic Engineering from Shanghai Jiao Tong University. Before joining HPArch, I worked in the MARS lab as the last "Martian", advised by Dr. Hsien-Hsin S. Lee and co-advised by Dr. Bo Hong.
