“It is rewarding to work in the healthcare sector because ultimately you’re allowing new technologies to be commercialized so that they’re available to help people. Otherwise, just like many other endeavors, if there’s no commercial incentive, if there’s no patent protection, the invention or good idea never sees the light of day. It’s just all the more important, I think, in healthcare that new technologies and ideas are protected and made available.”
