Paper to mentionMention their NSERC grant from 2024

Subject: Prospective PhD student: Decontamination Dear Professor Warriner, 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 "Inactivation of Pseudomonas Enveloped Bacteriophage Phi6 (H5N1 Surrogate) in Raw Bovine Milk using a Combination of Ultraviolet light (254 nm), Advanced Oxidative Process, and Endogenous Lactoperoxidase System." (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 "Gas phase hydroxyl-radical process for inactivating parasites (protozoan and enteric viruses) on fresh or frozen vegetables" (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]
