I am a Lecturer in Philosophy. Much of my research has investigated how incorporating insights from philosophy of language and linguistics can illuminate broader philosophical debates. My paper "Normative Language in Context" (Oxford Studies in Metaethics, Vol. 12, ed. R. Shafer-Landau), which was awarded the Marc Sanders Prize in Metaethics, applies this project to the case of normative language and metaethical debates about moral disagreement, judgment, and truth. In 2016 I completed a book, Discourse Contextualism (OUP), which defends contextualism about a range of expressions that have figured in contextualism/relativism debates (e.g., epistemic and deontic modals, gradable adjectives, and evaluative predicates). Other projects include work on questions, mood, Nietzsche, and vagueness. I am currently completing a book manuscript, Semantics with Assignment Variables, which develops a systematic compositional semantics for various linguistic shifting phenomena, such as with quantifiers, attitude ascriptions, relative clauses, questions, and conditionals (view current draft).

I joined the Philosophy Department in 2013 after completing my PhD in philosophy at the University of Michigan. My research is primarily in philosophy of language, ethics, and metaethics. In 2018 I finished a 2.5-year AHRC Research Grant with Daniel Rothschild (UCL) on Context-Sensitivity in Natural Language. In 2019–20 I took up a Leverhulme Research Fellowship. My 2016 book, Discourse Contextualism (OUP), defends contextualism about a range of expressions that have figured in contextualism/relativism debates. I am currently working on a systematic compositional semantic framework which posits explicit representations of context in linguistic structure and meaning. My forthcoming book, Semantics with Assignment Variables (CUP), develops the framework and applies it to diverse linguistic shifting phenomena, such as with quantifiers, attitude ascriptions, relative clauses, questions, and conditionals. Other projects include work on adjectives, questions, mood, Nietzsche, and vagueness.
