I am an assistant professor in cyber risk at Delft University of Technology, Faculty Technology Policy & Management, section Safety & Security Science. I studied computer science and philosophy of science, technology and society at the University of Twente, and wrote my interdisciplinary PhD “La volonté machinale: understanding the electronic voting controversy” at the Radboud University Nijmegen. Afterwards I advised the Dutch Ministry of the Interior on electronic voting and electronic travel documents. From September 2008 until December 2011 I worked in the VISPER project at the University of Twente, concentrating on disappearing boundaries in information security. In 2012 I was involved in the SESAME project at Delft University of Technology, addressing decision support for security investments in electricity infrastructures. Together with Prof. Pieter Hartel I set up the TREsPASS European project, on cyber security risk management in socio-technical systems, which started in November 2012. I was program chair of the 2010 CPDP workshop on Security and Privacy in Cloud Computing, program co-chair of the First International Workshop on Graphical Models for Security (GraMSec 2014), and co-organised the Dagstuhl seminars on Secure Architectures in the Cloud (2011) and Socio-Technical Security Metrics (2014). I published on electronic voting, verification of security properties, information risk management, and philosophy and ethics of information security.
