About

This is the personal homepage of Mattijs Jonker.

I am a PhD candidate at the University of Twente, where I work in the Design and Analysis of Communication Systems (DACS) group. My research is on Distributed Denial-of-Service (DDoS) attacks, with particular emphases on attack characterization and cloud-based mitigation solutions. Much of my research is done in collaboration with the Center for Applied Internet Data Analysis (CAIDA), where I spent nine months as visiting researcher in 2017 and 2018.

I work on the OpenINTEL project, in which we measure a large part (~60%) of the Domain Name System (DNS) for academic research. We make data available to academic researchers upon request and also share datasets publicly for the benefit of the research community.

My areas of expertise include Internet measurement, network security and intrusion detection. I hold a Master of Science in Computer Science with a specialization in cyber security.
