I am an associate professor at the University of Southern California. My main interests are in metaphysics, epistemology, the philosophy of language and philosophical logic. I have recently completed a book on vagueness entitled "Vagueness and Thought", and I am presently writing a book on higher-order logic aimed at philosophers.

Much of my recent work focuses on what it means for a property, relation (or operation of some other type) to be *fundamental* and what it means for one property, relation, etc. to be built out of, or *metaphysically definable* from, some others. Underlying a lot of this work is an abstract analogy between languages and reality that is most naturally cashed out using category theory (spelled out in the paper Substitution Structures). My views on the metaphysical issues are outlined in the paper Logical Combinatorialism and The Broadest Necessity.
