Subject: Prospective PhD student: Streptococcus Suis Dear Professor Gottschalk, 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 "SSU_RS09155, a virulence-associated gene encoding a putative membrane of unknown function, that is essential for Streptococcus suis serotype 2 virulence." (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 "Studies on the pathogenesis of the infections caused by Streptococcus suis" (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]
