Hello! I am a SSHRC doctoral fellow and PhD candidate at the Department of Philosophy and Joint Centre for Bioethics at the University of Toronto, and a Massey College Junior Fellow. I have a Bachelors degree in International Relations from the University of Toronto, during which I focused on global health governance. My current research focuses on issues around medical decision-making, physician-patient communication, and informed consent.
A central topic of my work is that the validity of a choice is not determined by the nature of the options, rather by how the decision-making environment is constructed.
Beyond my dissertation work in clinical bioethics, I am also interested in public health ethics, especially issues related to patient advocacy for immigrant and minority communities. I currently serve as a board member on the University of Toronto’s Health Sciences Research Ethics Board. I am also a ethicist facilitator for the Temerty Faculty of Medicine’s Ethics and Professionalism seminars.

This article examines how technical terminology in public-facing communication creates epistemic barriers that undermine trust between experts and the public—especially in multilingual, multicultural healthcare systems. It argues that health leaders can foster trust by employing a “code-switching” model within institutions and in patient- or public-facing communications. Code-switching is a linguistic phenomenon in which individuals switch between languages, dialects, or language varieties based on the social context. Recognizing “public-speak” and “medical-speak” as distinct codes would facilitate patient understanding of information relevant to their care and promote trust. Health leaders play a crucial role in ensuring that complex medical information is translated into accessible language, bridging the gap between experts and the public.

In many jurisdictions, legal frameworks afford patients the opportunity to make prospective medical decisions or to create directives that contain a special provision forfeiting their own ability to object to those decisions at a future time point, should they lose decision-making capacity. These agreements have been described with widely varying nomenclatures, including Ulysses Contracts, Odysseus Transfers, Psychiatric Advance Directives with Ulysses Clauses, and Powers of Attorney with Special Provisions. As a consequence of this terminological heterogeneity, it is challenging for healthcare providers to understand the terms and uses of these agreements and for ethicists to engage with the nuances of clinical decision-making with such unique provisions surrounding patient autonomy. In theory, prospective self-binding agreements may safeguard patient’s “authentic” wishes from future “inauthentic” changes of mind. In practice, it is unclear what may be comprised within these agreements or how—and to what effect—they are used. The primary focus of this integrative review is to curate the existing literature describing Ulysses Contracts (and analogous decisions) used in the clinical arena, in order to empirically synthesize their shared essence and provide insights into the traditional components of these agreements when used in practice, the requirements of their consent processes, and the outcomes of their utilization.

The aim of a theoretically ideal process of informed consent is to promote the autonomy of the patient and to limit unethical physician paternalism. However, in practice, the nature of the medical profession requires physicians to act as ontological decision architects—based on the medical knowledge that they acquire through their experience and training, physicians ontologically determine a subset of viable courses of action for their patient. What is observed is not an unethical physician limitation or biasing of the patient towards certain treatment options that violates patient autonomy or consciously undermines informed consent, but rather a more foundational paternalism that is necessarily inherent to the physician–patient relationship. In this article we argue for a recognition of this underlying physician paternalism and posit that this necessary paternalism is not a foil to patient autonomy, but rather a foundational aspect of the duties of the medical professional within the physician–patient relationship.

Our objective is to examine the role of explainability in machine learning for healthcare (MLHC), and its necessity and significance with respect to effective and ethical MLHC application. Ultimately, we conclude that the value of explainability in MLHC is not intrinsic, but is instead instrumental to achieving greater imperatives such as performance and trust. We caution against the uncompromising pursuit of explainability, and advocate instead for the development of robust empirical methods to successfully evaluate increasingly inexplicable algorithmic systems.
