It's a nascent area, so solid references are scant. I hope to remedy that myself some day.
A better known author on the topic is Bruce Lipton, whose 2006 book The Biology of Belief [1] introduced these concepts to a broad audience.
I've found the book insightful and helpful, but whilst he's a credentialed scientist himself (former cell biology researcher at Stanford School of Medicine), he gets hand-wavy about concepts like epigenetics and quantum entanglement and leaves himself vulnerable to attack from mainstream skeptics.
Still, I recommend the book for anyone who is able to overlook that. The science may be unclear but the core principles and healing techniques are solid, in my experience of applying them over the past 6+ years.
