My research primarily focuses on security areas such as web security, system security, and program analysis. My prior work focused on web tracking, but now is directed toward static/dynamic analysis and privacy -- trying to solve real-world challenging problems such as increasing the accuracy and efficiency of vulnerability detection, mobile APP analysis and privacy protection.
