Subject: Prospective PhD student: Clinical Dear Professor Nair, 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 "MAX-SHOCK: A Pragmatic Randomized Controlled Trial Comparing Biphasic Defibrillators Used in Routine Cardioversion of Atrial Fibrillation." (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 "Ablation Strategy for Paroxysmal Atrial Fibrillation - Trigger and Substrate Guided Wide Area RadiofrEquency Ablation Compared to Cryoablation Pulmonary Vein Isolation- A Patient Specific Precise Approach To Paroxysmal Atrial Fibrillation Ablation: AWARE-2 RCT" (2022), 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]
