I am a Professor of Philosophy at the University of Glasgow. Before that, I worked at the University of Nottingham and at Jesus College, Cambridge. I hold a PhD in Philosophy from the University of Sheffield, and a BA and MPhil in Philosophy from the University of Cambridge. My research is primarily in social philosophy, especially the ontology of social categories. I'm interested in how social categories such as races and genders exist, and how these categories are bound up with systematic injustices. I'm also interested in feminist philosophy and critical philosophy of race more broadly, in the philosophy of sex and sexuality, and in social epistemology.
