What does this mean (post-acceptance)?

[Vidoory]

Hi everyone, 

 

I'm looking for some advice and input on what this situation could mean. I was accepted into the PhD program of my choice a while ago, and went in for "interviews" with some of the PIs whose research interested me and who I wanted to do rotations with a week ago. There was this one particular PI whose research I loved, and I also thought our meeting went really great (and I mean like one of the best interviews I've ever had type thing). Even though he didn't specifically say anything about me doing a rotation in his lab, he did describe potential projects for next year. I felt great about that meeting at the time, and sent him a thank you email the day after our meeting to reiterate my interest in his research, but have not heard back from him after a week. Just to clarify, he is not a super busy PI that might just not have time to reply to emails, but only newly established. Although there are a lot of other amazing researchers in this program who I would be considered lucky to work with (most more prestigious), I can't help but feel a little depressed because I find this PI's research truly exciting, and have already read so much into the topic just for my own interests. Do some PIs just not reply to thank you notes/emails (even though I did phrase my last sentence as more of a question of whether I could do a rotation in his lab), or do you think maybe our meeting really didn't go as well as I originally thought? I have had my fair share of interviews in the past, and all of the ones I was successful at had quick replies to my emails, and even one who reached out to me without anything done on my part, that I'm feeling a little hopeless at the moment. Also, do PIs normally invite students to do a rotation in their lab at the first meeting, or is this something I should have brought up? I'd appreciate any input! Thanks!
