BS, MS, PhD Cornell. His current research is focused primarily in the philosophy of mind, specifically on propositional attitudes. To this end, he has been concerned to develop a measurement-theoretic account of the semantics of propositional attitude predicates (Measure of Mind, Oxford 2007) as well as a dispositionalist account of the attitudes themselves. He continues to be interested in issues in the foundations of cognitive science, especially as they have to do with linguistic competence.
