(2026), and it connects closely to my own work on [your research topic]. [One or two sentences on what you did and what you learned.] I also saw your CIHR-funded project "Bridging the Waiting Period in Metabolic and Bariatric Surgery Through Knowledge: An Interdisciplinary, Patient-Oriented Research Approach for an Online Education Platform" (2025), and I would be glad to contribute to work in that direction. Are you accepting new PhD students for [term and year]? I have attached my CV and transcripts, and I would be glad to talk at a time that suits you. Thank you for your time. Kind regards, [your name]
