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. I was previously a postdoc on the project New Agendas for the Study of Time: Connecting the Disciplines at the University of Sydney's Centre for Time, researching on the philosophy and physics of the arrow of time. In 2013, I achieved my PhD in Philosophy at the University of Bristol under the supervision of James Ladyman.

I work on conceptual issues concerning time, causation and explanation, particularly what it means for time to 'have a direction' and what this has to do with various time symmetries and asymmetries in philosophy and physics. I have some unusual views on the distinction between past, present and future (including a stubborn belief that the past is as 'open' as the future), and an interest in novel perspectives on standard philosophical problems offered by 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 (with Sam Baron); 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.
