I'm a Senior Research Fellow in the Information Security Group of the Department of Computer Science at University College London.

The main theme of my research is to find ways to understand and model the behaviour of systems at all scales. By using ideas from security economics, statistics, game theory, and systems modelling, we can gain insight into how systems function and how they can be better managed. This can be used, for example, to explore how different policy choices will affect the security of an organization, or to understand how difference online communities influence the spread of information around the web.

I teach the Philosophy, Politics, and Economics of Security and Privacy on the InfoSec MSc programme. The moodle page for students is here.

I am a member of the International Data-driven Research for Advanced Modeling and Analysis Lab.
