Subject: Prospective PhD student: Adaptation des microorganismes Dear Professor Labrie, 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 "Genomic insights and antifungal potential of Pseudomonas species isolated from maple sap, including the novel species Pseudomonas acericola sp. nov. and Pseudomonas edsoni sp. nov." (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 NSERC-funded project "Étude des interactions dans les microbiotes alimentaires complexes" (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]
