Research Focus

My research focuses on interventions related to polypharmacy, medication safety and dosing strategies. A number of my studies on the appropriate use of hospital resources, tests and treatments have been published in high-impact peer-reviewed journals and several relating to safer prescribing in older adults have been featured in the media. In 2020-2021 I participated in and led a number of high-profile COVID-19 studies. I happily supervise graduate students in the field of medication safety/optimization and have received funding from the CIHR, the Centre for Ageing and Brain Health Innovation, the Canadian Frailty Network and from the McGill Interdisciplinary Initiative in Infection and Immunity (MI-4).
