I am a professor of philosophy and associate department chair of philosophy at the University of St. Thomas in St. Paul, MN. I work primarily on medieval philosophy. Topics I have worked on include causation, modality, truth, God’s foreknowledge and causation of created actions. I have published on a variety of figures, including Thomas Aquinas, John Duns Scotus, Peter Olivi and Thomas Bradwardine. I also have interests in early modern philosophy, metaphysics, philosophy of religion and history of science.

I recently published a book Aquinas on Efficient Causation and Causal Powers with Cambridge University Press.  I am currently working on a second book called Divine and Created Causation in Medieval Philosophy. I am the current President of the Society for Medieval and Renaissance Philosophy and an Assistant Editor for the American Catholic Philosophical Quarterly.
