I am applying for a PhD position starting in [term and year]. I read your paper "Cerebral Venous Sinus Thrombosis in Pediatric Critical Care." (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 "Race, Ethnicity, Indigenous identity and Language preference for Pediatric research in the hospital setting (REIaL-P)" (2023), 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]
