Where were you educated?

S.T.L. Pontifical Faculty of the Immaculate Conception

What classes do you teach? 101-102 Fundamentals of Catholic Doctrine I-II. Upper-level courses according to the department needs. Departmental needs to date have included 411 De Gratia and 451 General Councils.

What is your favorite class to teach? If forced to pick, I'd say 102: It spends a fair amount of time on moral theology which tends to generate a lot of good questions. Also, it gives me a chance to be creative with my examples.

Do you have any hobbies? Gastronomy. Philology. Computer programming, especially C.

What do you like most about Christendom? It truly is an honor to work with such all-around great faculty. It's also a real pleasure having students that genuinely care about what I am teaching, even when it's a required course outside of their major.

Areas of Expertise and Research? Generically speaking, Thomism, Systematic Theology, and Moral Theology. More particular areas of research interest include the specification of moral acts in St. Thomas and his commentators, natural law theory, Molinism, analytic philosophy, and contemporary atheism.

Professional Associations and Activities? American Catholic Philosophical Association.
