Thesis title: Conscience and the Moral Permissibility of Institutional Conscientious Objection
Supervisors: Dr Tom Douglas
This thesis considered whether healthcare institutions should have a legal right to opt-out of the provision of medical procedures that violate their ethical standards or mission. Specifically, I consider whether a healthcare institution’s right to conscientious objection is morally contingent on it having a conscience.

2016 – 2020
Thesis title: Meeting Needs and Respecting Persons: An Ethical Framework for the Allocation of Lifesaving Healthcare Resources
Supervisors: Dr Steve Matthews, Dr Stewart Braun.
The thesis addressed the question, “How can we allocate health resources fairly under conditions of scarcity?”. I argued in favour of a contractualist approach to resource allocation inspired by the work of Stephen Darwall. I explored how this framework applies in two concrete scenarios: the allocation of medical care in a pandemic and the allocation of vital organs in organ transplantation programs.

2013 – 2015
Thesis title: Aquinas, Scotus and Ockham on the Knowledge of Singular Objects
Supervisors: Dr Paul Thom
In this thesis I compared three differing accounts of singular knowledge offered by philosophers during the High Medieval Period, namely, the accounts proposed by Thomas Aquinas (1225-1274), John Duns Scotus (1265-1308), and William of Ockham (1287-1347). By singular knowledge, I am referring to the cognition of singular objects qua singulars by the intellect.
