Professor of Computer Security and Head of the Department of Computer Science and Technology, University of Cambridge
Alastair is Professor of Computer Security and Head of the Department of Computer Science and Technology, often informally called The Computer Laboratory.
His research examines the security and privacy of large-scale distributed computer systems. Within this broad area, he is interested in the security and privacy of networked mobile devices, such as smartphones, tablets and laptops. He examines 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. He approaches this through the critical evaluation of existing products, by designing and building novel prototype technologies, and by measuring human behaviour.
