Joanna Schaffhausen wields a mean scalpel, sharp skills she developed in her years studying neuroscience. She has a doctorate in psychology, which reflects her long-standing interest in the brain―how it develops and the many ways it can go wrong. Previously, she worked as a scientific editor in the field of drug development. Prior to that, she was an editorial producer for ABC News, writing for programs such as World News Tonight, Good Morning America and 20/20. Additionally, she is the published author of three novels, including her most recent, "All the Best Lies." She lives in the Boston area with her husband and daughter.
