I am a Professor with the Department of Electrical and Electronic Engineering, The Hong Kong Polytechnic University. My research interests include adversarial machine learning, data privacy, database and network security, mobile, spatiotemporal and social databases. Aside from research, I lead the ASTAPLE lab, the PolyU CTF Team, and serve as the program leader of Bachelor of Science (Honours) in Information Security. I am a senior member of IEEE, ACM, and CCF. I am also a certified Cisco CCNA Security Trainer.
