Jarnevic teaches aesthetics, logic, contemporary philosophy, philosophy of religion, and various courses in metaphysics, especially philosophy of God and philosophy of the person. Jarnevic's area of specialization is philosophical theology with a particular interest in the epistemology of faith. His most recent scholarly work has dealt with a number of philosophical issues involved in St. Thomas Aquinas' theory of sacred theology or "sacra doctrina."

A further interest is the interplay of Thomism and phenomenology as regards the treatment of the human person in the philosophical writings of St. Edith Stein and Karol Wojtyla.
