Ph.D., Rutgers University, 1997


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.


Recent graduate seminars have included courses on metaphysical grounding, the history of analytic philosophy, physicalism, and the problem of consciousness. By way of undergraduate teaching, I have frequently taught courses in philosophy of religion, epistemology, metaphysics, and philosophy of mind. Currently I am recovering from eight (very long) years spent as Department Chair (2009-2017), which experience might best be described as a necessary evil.


If you are curious, you can check out my answers to the PhilPapers Survey here. If you are not curious, you can still do it, but it would be pretty silly of you to do so.

Take note:

"ItÕs been said in many places before: A degree in the humanities isnÕt exactly marketable to employers (less kind critics have called those degrees "useless"). But thereÕs one humanities major whose graduates are doing quite well in the job market—and itÕs philosophy majors."




Office hours for Fall 2017:

Mondays 12:00 PM - 3:00 PM

Teaching Fall 2017


PHI 2010 Introduction to Philosophy (Online)

Co-taught with Dr. Elizabeth Palmer


The patient and thorough exploration of philosophical questions is an ideal way to develop skills in clear writing and critical thinking. This course introduces the discipline of philosophy with a focus on developing those skills. Most of the semester is devoted three traditional issues: (a) What is knowledge? What can we know? (b) What is free will? Is there reason to think we don't have any free will? (c) What is morality all about? Are there facts about what is morally right and wrong? At the end of the semester, we will more briefly explore some famous questions about happiness and the meaning of life. The emphasis throughout is on writing clearly about such elusive questions and presenting good reasons to endorse one answer over another.

     The course provides 4000 words of credit towards the Writing Requirement at UF as well as satisfying the State Core General Education requirement for Humanities. Assignments include three argumentative essays, four short writing assignments, regular quizzes, and weekly activity assignments. Students are divided into smaller groups for the purpose of enabling both general discussion with each other and peer feedback on activity assignments. There are no major exams (no mid-term or final exam). No book purchases are required, as all readings are made available online through the Canvas system.

     This is an entirely online course. Because there is no regular meeting time during which we all meet to discuss the material, it is especially important to keep up with all assignments, to participate in discussion boards, and to ask for help when needed. While the structure of assignments is designed to ensure that students challenge themselves, it is also designed so as to minimize the amount of stress placed on any particular assignment. Success requires, instead, regular and serious effort throughout the semester.


PHI 6506 Seminar in Metaphysics: Physicalism

A graduate research seminar focusing on recent controversial topics related to physicalism. After a basic review of the issues, specific recent controversis will be decided, determined in part by student interest.
