Assistant Professor
Nguyen Phong Hoang is an Assistant Professor in the Department of Computer Science at the University of British Columbia (UBC), affiliated with the Systopia Lab and Security and Privacy Group. His research focuses on network security, online privacy, and Internet measurement, with particular emphasis on improving networked system security and reinforcing privacy through large-scale data collection. He has pioneered projects like GFWeb and GFWatch to measure China’s Great Firewall and other censorship mechanisms. Prior to UBC, he was a Postdoctoral Scholar at the University of Chicago under Prof. Nick Feamster, and completed his PhD at Stony Brook University under Prof. Michalis Polychronakis. His work has been supported by the OTF’s Information Controls Fellowship, enabling collaborations with groups like the Citizen Lab (U of Toronto) and UMass Amherst. He currently teaches courses on computer networking and network security at UBC. Research interests include DNS censorship detection, domain name encryption protocols (e.g., DNS-over-HTTPS), and methods to evade Internet censorship. His publications analyze global network interference, connection tampering, and the impact of encryption protocols on censorship resistance. He has developed tools like GFWeb’s interactive dashboard for longitudinal censorship monitoring and contributed to improving I2P (Invisible Internet Project) resilience against surveillance. Phong has also served on program committees for major conferences including IEEE S&P, USENIX Security, and IMC. Phong’s academic journey includes time at Kyoto University and JAIST in Japan, where he explored location privacy in dating apps and network anonymity. His interdisciplinary approach bridges technical cybersecurity solutions with policy implications, contributing to both academic discourse and public understanding of Internet freedom challenges.
