I'm a philosopher working on the ethics and politics of deep difference. My research asks how democracies can deliberate well when citizens disagree not just about policy but about what matters most. Religious difference is my central case because it's the most demanding one. Models that work there apply well to other intercultural contexts.

A second strand of my work asks what happens to public argument when its technology changes. I've written on the printing press after the Enlightenment, on deliberative forums under conditions of religious strife, and most recently on situated cognition — the idea that thinking runs through our tools, texts, and language rather than staying inside our heads. That last thread is my priority right now, given recent developments in AI.

I teach courses on democracy and diversity, philosophy of relationships, and the ethics of emerging technologies. Each aims to give students the philosophical skills to thrive in a diverse democracy. I also supervise research students in these areas.

From 2024-27, I am the Deputy Head of School Teaching and Learning in the School of Humanities, Creative Industries and Social Sciences, where I get to test the same ideas about deliberation on the institution in which I work.
