I am a Lecturer in Logic, Epistemology, and Metaphysics at the Department of Philosophy at the University of Sydney.

I am also the Department's Postgraduate Study Advisor. Please do contact me with all and any questions that you might have with regard to your plans for postgraduate study in philosophy (programs, funding, visas, accommodation, entrance exams, and so forth). This applies to current USyd students for all postgraduate philosophy plans, and to all non-USyd students who are considering USyd for postgraduate study in philosophy.

My area of research interest is Formal Philosophy, especially Formal Epistemology, Philosophical Logic, Philosophy of Language, Philosophy of Mathematics, and Philosophy of Information. Here is Maricarmen Martinez and my newly revised coauthored entry on Logic and Information at the Stanford Encyclopedia of Philosophy. I have a strong interest in the Philosophy of Music also.

I studied for my DPhil under Timothy Williamson and Luciano Floridi at Balliol College with the Faculty of Philosophy at the University of Oxford.

In the not altogether too distant past, I have been a Postdoctoral Research Fellow on the Formal Epistemology Project at the Department of Theoretical Philosophy at the Faculty of Philosophy at the University of Groningen, a lecturer in philosophy at St Anne's College, at the University of Oxford, a Visiting Research Fellow at TiLPS, at Tilburg University, a Postdoctoral Researcher at the Centre for Logic, University of Leuven, and a Senior Research Fellow with the IEG at the Department of Computer Science at the University of Oxford.
