• PhD. Philosophy, University of Leeds, Leeds, England, 2007.
• Taught M.A., Philosophy, University of Leeds, Leeds, England, 2001.

I studied at the University of Leeds, as well as worked there as a teaching assisstant and as the administrator for the CMM (Centre of Metaphysics and Mind.) I moved to Glasgow to take up a one-year temporary teaching post before then taking another temporary post at the University of Birmingham. I was made permanent the year after.

I teach both metaphysics and the philosophy of religion. 

I currently supervise doctoral candidates researching areas including metaontology, ontology, the philosophy of time, and the philosophy of mind. I can supervise theses in a wide variety of areas of theoretical philosophy, including metaphysics and many areas of philosophy of religion, science and mind. 

I’m currently completing the final draft of a book on the philosophy of time travel.
