Professor Miller usually teaches one course per semester through the Department of Religion. Students need not have a religious studies background or concentration to be eligible for the course. Depending on his schedule, he teaches Business Ethics and Modern Religious Thought (REL 219), and a course on one of the 20th century's most notable ethicists, activists, and theologians, called Dietrich Bonhoeffer's Life and Ethics: A Legacy for Our Times? (REL 314).
