In my academic life I am a crypto-physicist, that is, a cryptologist and a physicist. 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. I am the founding director of the Centre for Quantum Technologies (CQT) in Singapore. Outside academia I am addicted to all kind of water sports, general aviation, and I am partial to South African wine.
