Paper to mentionMention their CIHR grant from 2026

Subject: Prospective PhD student: Bioinformatics Dear Professor Armstrong, 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 "Reduced fibre-fermenting capacity of gut microbes in multiple sclerosis may result in prebiotic dietary fibre β-fructan promoting inflammation and CNS damage." (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 "Defining the molecular mechanisms underlying how consumption of specific ultra processed foods impacts disease progression, risk of surgery and post-operative recurrence in the CIDsCaNN Canadian national pediatric Crohn's disease cohort" (2026), 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]
