My research is interdisciplinary, spanning computer science, physics and the philosophy of physics. My main interests are in quantum information science and the foundations of quantum theory. My work focuses on developing new ways in which quantum systems can be used for tasks such as computation and cryptography, and on the use of tools from information science to address the conceptual problems of quantum theory.
