He was Alvin Plantinga Fellow in the Center for Philosophy of Religion at Notre Dame in 2005-06.

Dr Williams's research interests are in medieval philosophy and theology (especially Augustine, Anselm, Aquinas, and Duns Scotus) and the philosophy of religion.

Current projects include a translation of Augustine's Confessions, a translation of and commentary on Thomas Aquinas's Treatise on Happiness and Treatise on Human Action (co-authored with Christina van Dyke of Calvin College), and John Duns Scotus: Readings in Ethics, for which he recently received a $138,000 grant from the National Endowment for the Humanities.
