Susan Hart has published widely on attachment and neurobiology. She lives in Denmark.

"Susan Hart has unified her brilliant and compelling command of both the objective scientific and the subjective psychotherapeutic aspects of attachment into a cutting-edge synthesis that she calls developmental neuroaffective psychology. In this book Hart makes the often-confusing science of attachment highly accessible to both practitioner and researcher. The book’s contents are well balanced with a refreshingly adequate portion dedicated to translating theory into principles for treatment."
