I am a University Senior Lecturer in Computer Science at the University of Cambridge Computer Laboratory and a Fellow of Wolfson College.
Primarily a computer scientist by training, I also have backgrounds in electronics, digital signal processing, communications engineering, and physiology. My broader interests cover most aspects of applied computer science and technology, including neurophysiology and robotics.
My research and that of my PhD students has focused so far on computer security, in particular hardware and signal-processing aspects of this very wide field. Compromising emanations, RFID security, and the security of positioning systems (distance-bounding protocols, authentication of navigation signals) have recently been particular areas of interest. I also worked in the past on hardware tamper resistance, smartcards, network security, “intellectual property” protection technology (in particular pay-TV conditional access), data compression, video and audio technology, FPGA applications, and some standardization matters (character sets, semi-structured data, file formats, etc.).
