I work in the field of applied ontology. This work involves exploring interesting ideas from cognitive science, social psychology, mathematics, and analytic metaphysics and seeing how they might be useful in engineering ontologies–one of the key components of the semantic web. I received my ph.d. from the University at Buffalo, where I worked with Barry Smith and many of his associates at the National Center for Ontological Research (NCOR).
