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.


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.
