My principal interest and area of research lie in the field of the Philosophy of Religion. More precisely, my investigations center on the question of "faith and reason," especially as developed by Thomas Aquinas. I am currently exploring Thomas' thought on this topic in the light of questions posed by Frederick Nietzsche and Leo Strauss. In tandem with this, I am comparing the very different understanding of this topic expressed in two of the greatest works of Biblical interpretation ever written: Augustine's  De doctrina christiana  and Spinoza's Tractatus Theologico-Politicus .
