I'm a philosopher specialising in the metaphysics and epistemology of time and causation. I'm currently a Postdoctoral Research Fellow on the project The Causal Power of Information in a Quantum World at the University of Queensland and an 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 under the supervision of James Ladyman for my thesis Towards a C Theory of Time, examined by Huw Price and Alexander Bird.

My research covers various issues in philosophy of science, metaphysics, philosophy of physics and epistemology, in particular the relationship between the directionality of time and causation, the roles of non-causal constraints and self-locating beliefs in scientific explanation, and the relationship between science and metaphysics more generally. 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 overlap of philosophy and 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 recently coorganised the conference Causality in a Quantum World with my colleague Pete Evans. I have previously 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). From 2013-2014, I ran the Sydney Foundations of Physics seminar series.


I'm currently coordinating the following courses:


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