I sent an email to Columbia BME department regarding my application, and they told me they haven't reviewed it yet. (I applied for MS/leading to/Ph.D which was due on Dec).
I guess it will be some while before they make decisions.
One of the faculty members at UCLA told me that he reviewed my application, but he doesn't know yet which students were admitted. I wonder what this means......
Anyways, not a word from JHU.
Let's keep in touch =]
