Should I invite my professor, who is also my adviser for my doctoral program? I'm thinking I should, but I know her academically/professionally, not really personally. Though recently she has taken me more under her wing, so I feel an invite would be a nice gesture, even if she has no time to attend.
That leaves me with deciding whether to invite the other two professors in the same department: they've both written me letters of recommendation and worked with me one on one, but I don't keep in touch with them regularly or on a personal basis. I haven't really talked with one of the professors for several months. If I invite one professor, should I invite all three? Since they work in the same department, I believe they might hear about it.
By the way, the number of guests is not a problem right now. I think I have room for everyone.
Thanks!
