I am an assistant professor at the cyber security group at Delft University of Technology, and head of the Delft Threat Intelligence Lab. My research interests include internet measurements, network security, and cyber threat intelligence. During my PhD I studied for two years at the Hasso Plattner Institute in Potsdam, Germany, and finished the PhD at Delft University of Technology.
