Aristotle says that philosophy begins in wonder.  As it turns out, I couldn't restrict my wonder to just one domain of philosophy!  As a result, my research ranges from philosophy of religion to epistemology to ethics.  But no matter the field, my goal is to produce clear, non-technical philosophy that helps us to think better about the world in which we find ourselves.  In recognition of this work, I received the university-wide research award in 2018-19.
