I am interested in understanding how people use networked systems, and using this information to build better systems. My research has involved measurements and testbeds for networked games, wireless networks, mobile sensors, smartphones, online social networks and opportunistic networks. More recently I have become interested in the privacy and ethical aspects of such research, which has in turn led to an interest in the law. I took a sabbatical to study for a law degree and am now focused on how technology, ethics and the law can be jointly used to regulate behaviour.

Privacy, data ethics, data protection, law and technology, human-data interaction (HDI), online social networks, reproducible and responsible research

I am an interdisciplinary computer scientist with training in computer science (MSc and PhD, UCL), economics (MA, Cambridge) and law (LLM, Edinburgh). My current research interests include data protection, privacy and digital rights, and I co-lead our School's Responsible and Sustainable Computing research theme. Teaching interests include my popular module on data ethics. Prior to joining St Andrews in 2006, I worked at Dartmouth College (Department of Computer Science and the Institute for Security & Technology Studies) in the USA.

I welcome opportunities to work with organisations and policymakers around the responsible use of data. I currently sit on the Young Scot Data Advisory Group and am an Area Editor for Data & Policy.

I am less involved in the School of Computer Science at the moment, as I am currently serving as the Associate Provost (Students) in the University, as well as the Director of Teaching in the Graduate School. As such I am afraid that I am unable to supervise taught student projects, although I am happy to consider applications from qualified research students.
