My main interests are in questions about the nature and structure of thought, experience, and the self. I'm particularly interested in the various notions of representation in philosophy and cognitive science. Are representations explanatory posits? Data of introspection? What explanatory work do representations do in their respective fields? And can the existence and nature of mental representations illuminate other problems, e.g. debates over metaphysical realism, or the nature of the self? These concerns also bring me into contact with questions in the philosophy of science, language, and metaphysics.
