Subject: Prospective PhD student: Inflammatory Bowel Disease 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 "β-Glucan and Inulin Estimated Intake Are Associated With Reduced Risk of Crohn's Disease, Improved Gut Barrier and Systemic Inflammation Markers, and Multi-Omic Signatures in a High-Risk Cohort" (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 "Uncovering how ethnic diversity in diet and environmental factors in a Canadian pediatric Crohn's disease population underlies the role of host and microbiome in pCD progression, surgery and post-operative recurrence" (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]
