Paper to mentionMention their CIHR grant from 2022

Subject: Prospective PhD student: At-Risk Populations Dear Professor Bhatnagar, 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 "Transanal irrigation for the management of low anterior resection syndrome (LARS): protocol for a pragmatic, multicentre, crossover randomised controlled trial." (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 "iSampleSmart!, an innovative, App-facilitated self-sampling screen and treat strategy for common bacterial STIs (Chlamydia trachomatis and Neisseria gonorrhoeae) for Canadian key populations" (2022), 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]
