I am Professor of Computer Security and Head of the Department of Computer Science and Technology, often informally called The Computer Laboratory. I am also the Robin Walker Fellow in Computer Science at Queens' College, Cambridge.

My research work examines the security and privacy of large-scale distributed computer systems. Within this broad area, I am currently interested in the security and privacy of networked mobile devices, such as smartphones, tablets and laptops. I examine the security of the devices themselves as well as the security and privacy problems induced by the interaction between mobile devices and cloud-based Internet services. I approach this through the critical evaluation of existing products, by designing and building novel prototype technologies, and by measuring human behaviour.

Further information, including my papers, current research work and CV can be found on my personal web page.
