Asked, she said that she was assigned three advisors. but no specific lab.
Correction though, she was admitted to MIT for the Master's program, not PhD.
I am not sure, will have to ask. I know that they invited her for a visit, but it is the week before finals, and she hates flying, so she might decline.
Daughter just heard from Caltech/GALCIT today, she was "nominated for admissions" and formal letter will be sent by admissions office
she also got accepted to MIT, Stanford and USC, but Caltech is her number one choice, even over MIT
she attended both the Stanford tour last week and the GALCIT tour/interviews two weeks ago
