I am a Ph.D. candidate in Computer Science at Virginia Tech. My advisor is Dr. Danfeng (Daphne) Yao. Before I came to VT, I completed my Bachelor's Degree in Information Security from University of Science and Technology of China in 2013.
My research interests focus mainly on leveraging Program Analysis and Machine Learning techniques to address Cyber Security challenges. My work focuses on detecting Android malware with machine learning and app prioritization/rewriting. Additional research interests consist of anomaly detection, malware detection and intrusion detection.
[4/2017] I will have my prelim in the topic of Android mobile rewriting and its security applications in May-2017.
[4/2017] I will go to RSA industry research lab as a R&D intern this summer. Have a productive summer!
[1/2017] I am looking into Deep Learning for Mobile Security and anomaly detection.
[1/2016-6/2016] A visiting student in UCSD, San Deigo, CA. A wonderful place for tourism!
[10/2015] Check our current achievement on rewriting a malware behavior! [YouTube]
