Research overview
My research focuses on theories of meaning and reasoning, and their role in communication. I use logical, computational, and experimental methods to bring together the insights of linguistic semantics & pragmatics with philosophical and psychological work on reasoning and decision making. Much of my work has focused the use of probabilistic models to illuminate linguistic phenomena such as vagueness, presupposition, implicature, and the lexical semantics of modals and conditionals.
