The address matches. From the replies below, I'm not worried as much now. I did also email Heidi Williams, who was supposed to be "in touch for logistics". I'll talk to my supervisor tomorrow, who knows quite a few of the faculties, and hopefully he could help me figure out what's going on.
Has anyone been accepted by UC Davis?
I got an email from Prof. Aldo Antonelli saying that I've been offered admission, with details to follow. That was two weeks ago. No detail has followed (no official offer or detail on funding). I sent two follow up emails inquiring on visiting schedules (which was "tentatively" scheduled for next week). No reply yet. I've seriously started to entertain the possibility of a spam or a joke...
Anyone else been accepted by Davis? Or know what's going on?
