My research focuses on cyber security risk management in complex systems. I work with qualitative and quantitative socio-technical security models, attack models, and attack graphs, to discover and prioritise weaknesses, and evaluate countermeasures. In relation to such decision support, I am also interested in the ethics of cyber security. I address electronic voting, cloud computing and electricity infrastructures as cases.

My research is part of the TRESPASS project.
