My research interests include bioethics, philosophy of medicine, and personal identity.

Previously, I have worked on emerging biotechnology ethics, overdiagnosis, defining disease, the epistemology of surgery, therapeutic goods regulation, and drug policy. My doctorate examined psychological continuity and narrative theories of personal identity.

Plan for future research include projects on ethical and epistemic issues related to personalised medicine, and the ethics of recreational drug use. In the longer term, I also plan to continue work on narrative identity.
