Alastair Beresford is Professor of Computer Security and Head of the Department of Computer Science and Technology (The Computer Laboratory) at the University of Cambridge. He is also the Robin Walker Fellow in Computer Science at Queens' College, Cambridge. His leadership spans both academic administration and research innovation within one of the world's leading computer science departments. Professor Beresford's research focuses on the security and privacy of large-scale distributed computer systems, with particular emphasis on networked mobile devices such as smartphones, tablets, and laptops. His work examines both device-level security and the privacy implications of interactions between mobile devices and cloud-based services. His methodological approach combines critical evaluation of existing products, development of novel prototype technologies, and empirical measurement of human behavior in security contexts. His recent publications reveal a strong focus on confidentiality computing, anonymity networks, mobile security, and secure group communication. Notable projects include Pudding (private user discovery in anonymity networks), CoverDrop (secure whistleblower-journalist communication), and research on the practical viability of anonymity networks on smartphones. His work consistently bridges theoretical security concepts with practical implementations that have led to real-world security improvements in iOS, Android, and OpenSSH. Scientific Awards: Andreas Pfitzmann Best Student Paper Award (PETS 2022) for work on secure initial contact between whistleblowers and journalists Professor Beresford leads several major collaborative research initiatives including the Centre for Mobile, Wearable Systems and Augmented Intelligence (co-directed with Prof Cecilia Mascolo), the Cambridge Cybercrime Centre, and the Raspberry Pi Computing Education Research Centre. He also serves as technical director for the Isaac Learning Platform, which has supported over 500,000 users making more than 120 million question attempts since 2015. His research has practical impact, with findings leading to security fixes in major commercial products including iOS 12.2 (CVE-2019-8541), watchOS 5.2, Android 11, and OpenSSH 9.8 (CVE-2024-39894).
