I'm, among other things, a semanticist, currently an assistant professor in the Department of Philosophy at Carnegie Mellon University. My more specific interests include the semantics of questions, attitude ascriptions, presupposition projection, the foundations of formal semantics, and philosophy of gender.

At the moment, this site is somewhat sparse, but you may wish to have a look at one of the following:

‘A fish-trap is for catching fish; once you've caught the fish, you can forget about the trap. A rabbit-snare is for catching rabbits; once you've caught the rabbit, you can forget about the snare. Words are for catching ideas; once you've caught the idea, you can forget about the words. Where can I find a person who knows how to forget about words so I can have a few words with him?’

‘But questions, I've learned since, can be like ocean currents. Wade in a little too far and they can carry you away.’
