American Jungian analyst who wrote The Inner World of Trauma — the most influential Jungian account of the psyche's response to early trauma — arguing that the psyche protects itself from overwhelming experience through a daimonic self-care system that simultaneously protects and imprisons the traumatized inner child.

Developed the Jungian theory of psychic defense against trauma — the 'self-care system' (not Jung's Self) that splits off the traumatized core and creates a protector/persecutor daimon — explaining why survivors of early trauma simultaneously protect themselves with defenses that are also their prison.
