Congratulation to you too. I interviewed with the PI mentioned in my SOP, so I believe he is going to be my PI. However, there is no information about funding. I reached out the PI i've been talking to inform him of my admission and ask about funding. He said the mail funding is usually sent separately and that most PhDs are usually fully funded. So let's wait and see. Would you be accepting the offer?
Congratulations on your acceptance to the Umass Epid program. How soon after your interview did you get a decision on admission? Did you get any information about funding?
