I'm a DPhil candidate in Philosophy at the University of Oxford. My research is supervised by Professor Guy Kahane and supported by the Ryle / T. H. Green Moral Philosophy Scholarship and a Global Priorities Fellowship. Before coming to Oxford in 2021, I completed an MSc in Philosophy and Public Policy at the London School of Economics and a BA in Philosophy at the University of Warwick.


At present, much of my research concerns normative nihilism. Though it has historically been loosely defined and much maligned, I believe that tight and interesting definitions of normative nihilism can be forged and that it is a view worth taking seriously.

Beyond normative nihilism, I have active interests in moral uncertainty and the moral foundations of effective altruism. My doctoral research synthesises these interests by asking: what effect does uncertainty about normative nihilism have on our reasons to 'do good'?

I am also interested in a number of issues in practical philosophy more generally, especially regarding consequentialism, immigration, and philosophical questions surrounding meaning in life.

Public Philosophy

Since 2022 I have co-hosted The Philosopher's Nest podcast along with Kyle van Oosterum. The Philosopher's Nest showcases the work, insights, and experiences of graduate students in philosophy.

Between 2019 and 2021 I hosted the Searching For It podcast. Searching For It explored various philosophical thoughts and themes that inform the search for meaning in life. Searching For It peaked at #2 on Apple Podcasts' daily Philosophy charts in the United States of America.
