Ask HN: Where to study bionics?

Hi HNers. There was a recent article about how Hugh Herr is advancing the field of bionics[0] (high tech prosthetics) Do you know what and where could I study to get in such interesting field? Is there any college that focus on this or has such career? Or if there is not what combination of careers would be the best equivalent?
