Bio

I am a third-year Ph.D. student in Department of Electrical Engineering at Princeton University, started from September 2013. I am advised by Prof. Prateek Mittal. I received both Master's degree and Bachelor's degree from the University of Science and Technology of China (graduated with Guo Moruo Scholarship, the highest honor in USTC).

Please find more about me in my CV, last updated June 2016.
