About this episode

Rosa Hart and Hamid Ghanadan discuss the importance of effective communication in healthcare and science.

Rosa Hart sits down with Hamid Ghanadan, behavioral strategist, researcher, and author of Not Buying It, to explore why science and healthcare have a usability problem - and what communicators, clinicians, and companies can do about it.
