I'm a DPhil candidate in Philosophy at the University of Oxford. My research is supervised by Professor Guy Kahane and Professor Roger Crisp 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.

Here's my CV.


My doctoral research concerns normative nihilism and its implications. I am currently interested in such questions as: "How can normative nihilists deliberate?"; "Is there a place for normative discourse after normative nihilism?"; "How 'should' we act under uncertainty about the truth of normative nihilism?".

I am also interested in a number of issues in practical philosophy more generally, especially regarding uncertainty in metaethics, duties of beneficence, and philosophical questions surrounding meaning in life.

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.
