Areas of research:  Metaphysics, philosophy of mind, physicalism, consciousness, a priori knowledge


Curriculum Vitae



I joined the faculty at the University of Florida in 1997 after doing my doctoral degree at Rutgers. My research has been in metaphysics and philosophy of mind, often focusing on the doctrine of physicalism, the claim, roughly, that everything that exists is in some sense ultimately physical in nature. I've also worked on such topics as the nature of intrinsic properties, questions about mental causation, functionalist treatments of the mind, and the role of conceptual analysis and/or a priori knowledge in metaphysics generally. My interest in epistemology and philosophy of religion has grown over the years and I might inflict my musings on such on the academic community in the future.


By way of undergraduate teaching, I regularly teach courses in epistemology, metaphysics, philosophy of mind, and philosophy of religion. Recent graduate seminars have included courses on metaphysical grounding, the history of analytic philosophy, physicalism, and the problem of consciousness.


If you are curious about my philosophical views, you can check out my answers to the PhilPapers Survey here. By an astonishing coincidence, you can find out the true positions regarding many of those questions at the same location.
