My Ph.D. is from UMass (1993), and I have taught at Rochester, Syracuse, NYU, and Cornell. I specialize mainly in metaphysics (time, identity, mereology, modality, supervenience, fundamentality…). I also have research and/or teaching interests in philosophy of language, logic, philosophy of logic, philosophy of mathematics, and philosophy of physics. Recently I’ve been thinking about how the choice of conceptual tools for articulating metaphysical questions (e.g. modality vs fundamentality vs ground) affects how we answer those questions - especially questions about the metaphysics of science.
