I wouldn’t bother with GTek or JHU. I think they are out of reach for BioMedEng. If you were going for ElectricalEng perhaps, but their BiomEng is too much of a reach.
Reach - Duke, UPenn
Match - RPI, CaseWestern, Northwestern, Boston U, Rose H, Olin, Bucknell, Cooper. In that order.
It all depends on your financial limitations.
