Marwan Fayed

Dr. Marwan Fayed is a Senior Lecturer and Researcher at the University of St Andrews' School of Computer Science. His work focuses on network security, privacy-enhancing technologies, and internet architecture. He has contributed to projects like Topaz (CDN-scale DNS), ODoH (DNS privacy), and research on QUIC website fingerprinting defenses. His research spans topics such as connection tampering detection, IP decoupling in CDNs, and zero-knowledge proof-based authentication systems.

Key research interests include:

• Secure and scalable network infrastructure
• Privacy in modern web protocols (DNS, QUIC)
• Resilient internet architecture design

His publications highlight interdisciplinary efforts in network measurement, cryptography, and distributed systems. Collaborations include NSF-funded workshops on internet survivability and industry partnerships for practical privacy solutions.

Notable contributions include the ODoH standard proposal and the Topaz system for authoritative DNS management. His work often bridges theoretical research with real-world deployment challenges in large-scale networks.
