Dr Soteris Demetriou is a Lecturer (Assistant Professor) of Computer Systems Security at the Department of Computing at Imperial College London and the Director of the Applications, Platforms, and Systems Security Research Lab (apss).
His interests lie in the security and privacy of mobile and cyber-physical systems. By analyzing operating systems, networking protocols and side-channels his work has uncovered design flaws and severe vulnerabilities on the Android operating system, Amazon services and commodity IoT devices among others, affecting millions of users. In response, his work has introduced tools, methods, and end-to-end systems to improve end-user privacy and strengthen security on mobile systems.
These include tools using code analysis and instrumentation, natural language processing and machine learning for detecting mobile applications’ privacy leakage, security enhancements for the Android OS middleware and its underlying Linux kernel, fine-grained access control for smart-home IoT devices by combining network and mobile application information and a framework which leverages trusted computing principles to preserve the privacy of machine learning models on resource constrained devices, among others.
Dr Demetriou's work appeared multiple times in top international systems security conferences such as NDSS and ACM CCS but also in other systems and sensing conferences such as IEEE Infocom, ACM MobiSys and ACM SenSys. His work received prestigious awards, including a distinguished paper award at NDSS (‘18). His mobile systems security work is also close to practice and resulted in relevant patents. Currently, Dr Demetriou also works closely with Meta (Core Systems) on large scale distributed computing problems.
