I'm a lecturer of philosophy at Washington University in St. Louis.
My research deals with states and situations that muddle our minds, including some artificial minds. These include uncertainty, inconclusive evidence, ambiguity, doubts about our cognitive powers, disagreement, indeterminacy, incoherence, ambivalence, paradoxes, defective questions.
I also investigate the logic and semantics of sentences involving deontic expressions such as 'ought' and 'can', as well as ascriptions of attitudes featuring verbs such as 'think', 'doubt' and 'want'. These two types of sentence behave in mysterious but similar ways.
