I am a Postdoctoral Research Fellow on the project The Causal Power of Information in a Quantum World at the University of Queensland and external member of the Munich Center for Mathematical Philosophy. From 2013-2014 I was a postdoc on the project New Agendas for the Study of Time at the University of Sydney's Centre for Time. In 2013, I achieved my PhD in Philosophy at the University of Bristol.

I research on various issues concerning time and causation in metaphysics and philosophy of science, particularly the relationship between the directionality of time and causation, and the roles of non-causal constraints and self-locating beliefs in scientific explanation. I have some unusual views on the distinction between the past, present and future (including a stubborn belief that the past is as 'open' as the future), and an interest in the application of philosophical methods to quantum foundations. In a nearby possible world I make my living as a drummer.

My current project investigates the causal nature of quantum information, with researchers in philosophy, and theoretical and experimental physics. My work within the project concerns the applicability of different philosophical theories of causation to quantum mechanics and the metaphysics of quantum information. My previous project concerned the study of time across philosophy and the sciences, with focus on physics and experimental psychology (and everything inbetween).


I am currently co-organising the conference Causality in a Quantum World with my colleague Pete Evans. Until recently, I organised the Sydney Foundations of Physics seminar series. I have organised/co-organised the following conferences: Free Will and Retrocausality in a Quantum World (with Huw Price); Time Symmetry: A Unified Approach; The Present State of Presentism; Conventional Principles in Science (with Milena Ivanova).


I'm currently coordinating the following courses:


I'm very happy to be married to this fellow philosopher.
