Hi Irene,
To answer your question, based on my experience doing research at BUSM (Boston University School of Medicine) in a master's program, I truly had a blast with several professors and colleagues. As one of the best institutions in medical research, I am glad to be part of BU Terriers. And if you are interested in pursuing career in industry (biotech/pharma), staying in Boston, provides you a lot of opportunities for professional networking.
When is your interview? I also got invited for interview at BU PiBS. My interview is on Feb 18 (I wasn't available on Jan 29, although I'd like to pick the earliest session). If you've done it, how was it?
