I am currently working at Microsoft. I graduated from Computer Science at Virginia Tech 2018. 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.
[6/2018] I passed my thesis defense, cheers.
[6/2018] Our framework SquatPhish for squatting domain ident. and phishing page detect. is released (ง'̀-'́)ง.
[5/2018] Will join a Security/Detection Team at Microsoft Cheers
[4/2018] Our tool FrameHanger is released. ( •̀ .̫ •́ )✧
[2/2018] Passed my research defense. Currently working on Web security plus machine/deep learning.
[8/2017] I was a R&D intern at RSA laboratories, under Dell EMC. We plan to file a patent for my internship work.
[5/2017] I passed my prelim exam in May-12-2017. A milestone!
[7/2016] I was a research intern on Android Security at Qualcomm.
[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]
