My philosophical interests include religious studies (Islam, Judaism, Christianity) and ancient and medieval metaphysics and philosophical psychology as well as issues of the relation and interaction of philosophical and religious thought in the medieval period with special emphasis on Islamic/Arabic philosophy, its sources and its influence. I have taught graduate courses on Aristotle, Ancient and Medieval Philosophy of Mind, Philosophy and Religion in the Middle Ages, Arabic/Islamic Philosophy, Thomas Aquinas and more. Undergraduate courses I regularly teach include Theory of Ethics, Philosophy of Religion and courses in the History of Ancient and Medieval Philosophy. I have written on Aquinas, the Liber de causis, Averroes, al-Farabi, et alia. My translation of Averroes’s Long Commentary on the De Anima of Aristotle (Th.-A. Druart, subeditor) with Yale University Press appeared in 2009. Current projects include: (i) an annual international video collaborative graduate course on Thomas Aquinas and the Arabic Tradition at Marquette & at the Katholieke Universiteit Leuven's Institute of Philosophy; (ii) Aquinas and the Arabic Philosophical Tradition: The Commentary on the Sentences, Selected Translations with Commentary, 2 v., with R. E. Houser and L. X. López-Farjeat for Cambridge U. Press; (iii) Routledge Companion to Islamic Philosophy, co-editor with Prof. Luis Xavier López-Farjeat; and (iv) ongoing work with the Aquinas and ‘the Arabs’ International Working Group. I am also editor of History of Philosophy Quarterly.
