About me

I am currently a CS Master student at Georgia Tech , specializing in computer system and high performance computing. Before I moving to United States, I obtained my Honored Bachelor Degree from Shandong University and spent a year at Hong Kong University of Science and Technology as a research postgrduate student focusing on code conprehension and regeneration.

My research instests generally lies in System Field, especially in the field of software-hardware codesign.

I am very fortunate to be advised by Dr. Helen Xu, Dr. Jiasi Shen, and Prof. Weiguo Liu and worked with Dr. Xin He and Dr. Chaojian Li. They have set an example for me as a researcher —— always doing interesting things, pursuing own interests and sticking to them.
