I am a fourth-year Ph.D. student focusing primarily on areas of mobile security, Android malware, Android vulnerability, program analysis, and adversarial machine learning..

I am currently advised by Professor Lihua Xu in SQSLab-ECNU. In addition, I owe a big thanks to Professor Haojin Zhu (SJTU) and Dr. Minhui Xue for leading me into the field of security pertinent issues with his profound knowledge, not only has a significant influence on how I think, but also is my lifelong mentor. I am working closely with Dr. Minhui Xue on mobile security and adversarial machine learning.

I am also a visiting Ph.D. student (Research Assistant) at Cyber Security Lab of Nanyang Technological University in September 2016 to December 2018. During my visit in NTU, I am advised by Professor Liu Yang. In addition, I am working closely with Dr. Guozhu Meng, Yinxing Xue, Ting Su, and Lingling Fan.

I would like to thank Pwnzen Infotech Inc. for providing us with a copy of mobile malware to conduct the study, especially the co-founder Zhushou Tang for exchanging helpful industry experience.

In Android malware, I am working on Android malware detection and classification (StormDroid) using machine learning (both static and dynamic features with statistical metrics) (refer to ASIACCS 2016). I've developed KuafuDet (refer to MobiCom 2016, Elsevier Computers & Security 2017) for Android malware detection using machine learning in adversarial environment. We examine how machine-learning classifiers (e.g., DroidAPIMiner, DREBIN, and MaMaDroid) can be misled under different threat models. We proposed a malware detection system, termed Begonia (refer to CCS 2016), through Pareto ensemble learning to trade off classification accuracy and time cost.

In Android vulnerability, I am working on security implication detection in security-critical Android applications (e.g., mobile banking applications). We investigated the characteristics of these implications, and the changing trend over time.

In Android platform, we conducted a large-scale study to characterize framework-specific exceptions in Android applications, and implemented ExLocator, an exception localization tool, for Android applications. (refer to ICSE 2018).

In program analysis, we have developed a continuous verification system, termed Eunomia (refer to APSEC 2016) to bi-directionally check conformance of model and corresponding source code.
