If there's a particular scholar I'd like to study under how should I carry out my initial correspondence with them? I haven't yet sent out my applications but am wondering what kind of correspondence is acceptable between Phd dissertation supervisors and their potential students. Is it acceptable to visit them in person in their office, or would a simple email suffice. How might I make an impact through my initial correspondence? I'm referring to those scholars in the humanities I'm particularly drawn to studying under.
