I'm a Lecturer in Philosophy at the Australian National University. ​In 2019-2020, I was a Laurance S. Rockefeller Visiting Faculty Fellow at Princeton University. Before then, I was a Senior Lecturer in Philosophy at the University of Liverpool, and an Assistant Professor at Trinity College Dublin. My main research interests are ethics and political philosophy, with a current focus on the pandemic, population ethics, utilitarianism, AI, and punishment.

I also write for popular media. My pieces have been published in venues such as The New York Times, The Sydney Morning Herald, The Guardian, Salon, and The Conversation.
