I am an Associate Professor in the Department of Computer Science at the University of Oxford. I obtained my PhD (2008) and BSc (1st Class Hons. 2004) from the University of Cape Town, South Africa. I lead the Cyber Reality Lab.


My current research revolves around low power sensing, localization and signal processing in wireless sensor networks and embedded systems. I am driven by solving real world problems. In particular, I am working on developing magneto-induction (MI) as a key technology for communication and localization in areas where wireless and GPS fail, such as underground or indoors.
