Mattijs Jonker serves as an Assistant Professor in the Design and Analysis of Communication Systems group within the Faculty of Electrical Engineering, Mathematics and Computer Science at the University of Twente. His research focuses on critical infrastructure aspects of the Internet, with particular emphasis on network security, DNS infrastructure, and Internet measurement methodologies. Dr. Jonker maintains an active research profile with numerous publications in top networking conferences and journals.
Dr. Jonker's research interests center on network security with a special focus on DNS infrastructure vulnerabilities and defenses. His work explores DDoS attack mitigation strategies, DNS security extensions, IPv4 addressing economics, and network measurement techniques. He investigates how network operators can enhance digital sovereignty and strengthen network resilience, as evidenced by his longitudinal analysis during the Russia-Ukraine conflict. His research combines theoretical analysis with practical measurement campaigns to address real-world security challenges in Internet infrastructure.
Analysis of Dr. Jonker's recent publications reveals a consistent focus on DNS security and network infrastructure measurement. His work spans DNSSEC deployments, anycast routing performance, IPv4 leasing market dynamics, and DDoS attack characterization. A notable trend is his emphasis on empirical measurement approaches to understand complex network phenomena, often developing novel measurement methodologies like response-aware scanning for DNS infrastructure analysis. His research bridges academic inquiry with practical security applications, as seen in studies on email authentication mechanisms and parental control systems.
