I am a Professor with the Department of Computer Science & Technology and the National Key Lab for Novel Software Technology at Nanjing University. Prior to joining NJU, I were fortunate to work with many wonderful people in NEC Labs Princeton, Microsoft Research Asia, and Samsung Research America. I earned my Ph.D. in Computer Science from the College of William and Mary and received the Distinguished Dissertation Award.
My research interests span a broad range of topics in the space of security and systems. Currently I am focusing on deep learning & data security, system & network security, user & input privacy, intelligent mobile systems (AR, IoT, smartphone, etc.) & applications, and edge & cloud services.
