Bruce H. Lipton, Ph.D., bestselling author of The Biology of Belief, is a cellular biologist and former Associate Professor at the University of Wisconsin's School of Medicine. His pioneering research on cloned stem cells at Wisconsin presaged the revolutionary field of epigenetics, the new science of how environment and perception control genes.

His later research at Stanford University's School of Medicine revealed the nature of the biochemical pathways that bridge the mind-body duality. His new book, Spontaneous Evolution: Our Positive Future and a way to get there from here, with co-author Steve Bhaerman, will be out in September 2009.
