Ph.D. Washington University in St. Louis, 2003
He is interested in how empirical research in psychology, neuroscience, and linguistics can illuminate traditional philosophical questions about the mind, and in the foundations of the cognitive sciences, including their methods, theories, and models. The main focus of his research is concepts, particularly their structure, content, and acquisition, as well as the relations among concepts, perception, action, and language. This work also reaches into related areas in philosophy of language, especially those dealing with compositionality, context, and lexical semantics. He has also worked on issues in cognitive modeling, psychological explanation, cognitive architecture, and embodied/extended cognition. Recently he has been thinking about multiple realizability, mechanistic explanation, and the metaphysics of kinds.
