I am an associate professor of philosophy at the University of St. Thomas in St. Paul, MN. My areas of research are medieval philosophy, early modern philosophy, metaphysics and philosophy of religion. Most of my current research focuses on the topic of causation. My main project is book which retrieves Thomas Aquinas’s intriguing views on causal powers and efficient causation. I am also working on a series of articles which trace the medieval background to prominent ideas in early modern discussions of causation. I have interest in contemporary discussions of causation, particularly the revival of neo-Aristotelian “powers” theories. Topics I have published on include modality, truth, and divine concurrence. Thinkers whom I have published on are Thomas Aquinas and John Duns Scotus, as well as the lesser-known, but nevertheless important, figures Peter Olivi, Peter Auriol, and Thomas Bradwardine.
