I am a Professor and Associate Head of the Department of Electrical and Electronic Engineering, The Hong Kong Polytechnic University, and Director of PolyU Research Centre for Privacy and Security Technologies in Future Smart Systems (RCPST). 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, and the PolyU CTF Team. I am a senior member of IEEE, ACM, and CCF. I am also a certified Cisco CCNA Security Trainer. More information can be found in my CV.
