I am a Ph.D. student in the 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). I am broadly interested in statistical data privacy and IoT security. More specifically, I have recently worked on differential privacy, network graph obfuscation, Sybil defenses and attacks, IoT security and privacy, machine learning and signal processing.
