I emailed also Northwestern for BME, they told me the Recruitment day is at the end of March, and that they have sent out the majority of their acceptances. However, if you have not received a rejection, that means we are in the waitlist. Yes, they also told me the same, they expect to finish all decisions by early April or sooner. Which specific research are you more interested in guys?, Have you received some response from other universities for PhD in BME? JHU, CASE, Brown?
