Paper to mentionMention their CIHR grant from 2019

Subject: Prospective PhD student: Cluster Analysis Dear Professor Orban, 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 "Effect of personalized dorsolateral prefrontal cortex neuromodulation on default mode connectivity and working memory in schizophrenia spectrum disorders." (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 "Brain connectivity-based optimization of non-invasive brain stimulation to improve cognitive symptoms in schizophrenia" (2019), 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]
