I am currently Research Associate on the ERC-funded project Better Understanding the Metaphysics of Pregnancy. Previously, I have been a Research Fellow at the University of Southampton, a Postdoctoral Researcher at the Centre for Philosophical Psychology, University of Antwerp, and a part-time Lecturer in Logic at The Queen's College, Oxford. For my education, I completed a PhD at UCL, the BPhil at Oriel College, Oxford, and a BA at KCL, all in Philosophy.

Research interests and PhD supervision

  • The Self/Personal Identity
  • Metaphysics
  • Philosophy of Mind
  • Metaphilosophy
  • Philosophy of Biology

My research interests revolve around the metaphysics of human life. My work addresses questions concerning our persistence, our minds and our origins, as well as related issues in epistemology, metaphilosophy and the philosophy of biology. As part of the ERC-funded BUMP (Better Understanding the Metaphysics of Pregnancy) project, I am working on the mereology of pregnancy, immunological accounts of biological individuality, pluralism about biological individuality, and fission.
