OK, so assignment of advisors is not actually like the Sorting Hat at Hogwarts (too bad). Preference forms were due to the program office yesterday at 2:30, the committee met yesterday afternoon, and assignment sheets were posted on bulletin boards around campus by the time I got out of a visiting author's reading at 8:15. We first-semester students were assured (again) that the process was all about logistics, and not about personalities.
Given that, I am really happy about the advisor I was assigned. He was not originally on my short list based on the teaching statements (faculty descriptions of how they work with students) that I received prior to the residency: although I really liked what he said about his approach, he also stated that he responded to student packets with an mp3 recording and I thought that would make it hard to remember what was said. But I met with him during speed dating and asked about it, and came away reassured. His lecture at this residency was also great, and I'm looking forward to working with him.
Our first meeting, a group meeting with all of his assignees for this semester, is at 11:45.
