Subject: Prospective PhD student: Ex Vivo Lung Perfusion Dear Professor Humar, 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 "Cytomegalovirus (CMV)-Specific Cell-Mediated Immunity for Prediction of Postprophylaxis CMV Disease in a Phase 3 Trial of Letermovir Versus Valganciclovir Prophylaxis in Donor CMV-Seropositive/Recipient CMV-Seronegative Kidney Transplant Recipients." (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 "Pandemic Influenza Vaccine in Organ Transplantation (PIVOT Trial): SAFETY AND IMMUNOGENICITY OF PANDEMIC INFLUENZA VACCINE IN KIDNEY TRANSPLANT RECIPIENTS" (2024), 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]
