I'm currently Associate Lecturer at University College London. Previously, I have been a British Academy Postdoctoral Fellow at the University of Sheffield and an Alexander von Humboldt Postdoctoral Fellow at the Frankfurt School of Finance & Management. I completed my PhD at the University of Edinburgh.

My research is primarily in ethics and meta-ethics. I'm particularly interested in ethical thought and language, the structure and authority of practical normativity, and all things related to well-being (including interdisciplinary approaches). I also have a broader interest in philosophy of mind, philosophy of language, and metaphysics.
