My research interests are in bioethics and research ethics. Much of my work explores the ethics of randomized controlled trials (RCTs) in health. The physician has a duty of care to her patient that requires that she act and advise to protect and promote the patient’s health. Given this obligation, how can the physician ethically enroll her patient in an RCT in which the patient is allocated randomly to one of two or more treatments? I have written about Charles Fried and Benjamin Freedman’s solutions to this problem. In my own work, I explore the role of trust relationships involving the state, physician-researchers and patients in addressing the problem.

I also work on ethical and epistemic issues raised by innovative RCT designs. I have written about cluster RCTs, which randomize groups—such as nursing homes, hospitals or communities—rather than individuals, to interventions. Recently, I co-led a research team that produced the first ethical guidelines for cluster RCTs. I am currently funded by the Canadian Institutes of Health Research (2017-2021) to explore the ethics of pragmatic RCTs, which seek to inform patients, health providers and health system managers by evaluating treatments in real-world conditions.

 I am available to supervise students in bioethics and research ethics. Working with me, students will receive training in philosophical and interdisciplinary research, and they will have the opportunity to participate in an international research team comprising philosophers, biostatisticians and trialists.
