In my academic life I am usually labeled as a physicist, but every now and then I am also called a cryptologist, or a mathematician. My main research interest is information processing in quantum mechanical systems. It is a cross-disciplinary field bringing together theoretical and experimental quantum physics, mathematics, logic, computer science and information theory. My work is mostly theoretical but its results bear directly on issues of experimental implementation. Outside academia I am addicted to all kind of water sports, general aviation, and I am partial to South African wine.
