I am a professor of philosophy at the University of British Columbia. My work falls mainly within the philosophy of language and metaphysics, with implications for general philosophical methodology. My first book Necessary Intentionality (OUP 2012) brings central themes in the metaphysics of modality to bear on cognitive matters, most notably intentionality or aboutness. My second book Semantics, Metasemantics, Aboutness (OUP 2017) studies the relationship between metasemantics and truth-conditional semantics and offers an extended response to the threat of semantic indeterminacy. Recent reviews can be found here, here, and here. In the course of the second book I consider how to think of aboutness in relation to the scope and aims of semantic theory. This suggests a prior and more general concern with relations between theoretical representations and their represented subject matter in the study of language, thought, and elsewhere in philosophy. My most recent work is focused on theoretical representations in philosophy and how we should regard them: Philosophical Representation: Studies in Attitudinal Instrumentalism (Routledge, 2023).
