My main field of research is the philosophy of physics, in particular the philosophy of quantum theory, where I have worked on a variety of approaches, including modal interpretations (for my PhD), stochastic mechanics, Everett theory, de Broglie-Bohm pilot-wave theory, and spontaneous collapse theories, with a special interest in the theory of decoherence. Other special interests include time (a)symmetry, the philosophy of probability, issues in the philosophy of logic, and the topics of emergence, causation, and empiricism. I also work on the history of quantum theory and have co-authored four books on the topic, including a widely admired monograph on the 1927 Solvay conference. I am currently engaged in research across a range of these subjects, including heading an ERC Advanced Grant on “Niels Bohr for the 21st Century”.
