I am assistant professor at University of Twente’s Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS). My research is on network security in the broad sense and involves extensive data science and Internet measurement.

I also work as chief big data architect on the award-winning OpenINTEL project, in which we measure a sizable part of the Domain Name System (DNS) for academic research.
