I am Professor of Philosophy at the University of British Columbia. I am a generalist but have written mostly on the philosophy of language and adjacent areas, with particular emphasis on the history of analytic philosophy and special interest in 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. In the course of the second book I contemplate 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, which is the topic of my third book, Philosophical Representation (Routledge 2023).
