Subject: Prospective PhD student: Dialysis Initiation Dear Professor Lok, My name is [your name], and I am a [your current degree or role] at [your institution]. I am applying for a PhD position starting in [term and year]. I read your paper "Objective and subjective measures of sleep quality in patients with end stage kidney disease: A cross-sectional study." (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 "CANada in the INCremental dialysis to improve Health outcomes in people starting Hemodialysis (CAN INCH-HD) study: a randomized controlled trial" (2021), 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]
