Professor of Mobile Systems

Fellow of Jesus College

Mobile Systems Research Laboratory

I am a Full Professor of Mobile Systems in the Department of Computer Science and Technology and I head the Mobile Systems Research Laboratory. I am also the centre co-director for the Centre for Mobile, Wearable Systems and Augmented Intelligence. My interests are in the study of mobile systems, the learning from their data offline and on device and their applications, especially in terms of mobile health. I hold an ERC Advanced Research Grant (2019-2024).
