Interests

Teaching

My main teaching interests are in ethical theory, including meta-ethics, and Kant's ethics. I regularly teach Philosophy 210, Moral Thinking, a course focused on normative moral theories. I also teach a cross-listed course, Philosophy/Psychology 348, The Moral Mind, focused on issues at the intersection of ethics and the empirical sciences, particularly psychology.
