Most of my work is on the philosophy of language and formal semantics. My dissertation is about demonstratives; I argue that if we want to understand them, we have to look at a much broader range of uses than philosophers usually do, and I develop a semantic theory that will cover those uses.
I am also interested in metaphysics (I wrote a BPhil thesis on emergentism), as well as some of the philosophical themes in Russian literature.
In 2000, I co-founded a non-profit organization that I ran until 2010. In 2005, the organization became the US counterpart to Ayuda Directa, an NGO that is currently active in Ecuador.
