As an emeritus professor, he continued to teach and research and maintained a selective private practice in Palo Alto.
Steiner advocated the developmental psychopathology and developmental psychiatry perspective within psychiatry. He worked in the subfields of aggression, its normal and abnormal development; disruptive behavior disorders (such as conduct disorder, oppositional defiant disorder, attention-deficit hyperactivity disorder); eating disorders (anorexia nervosa, bulimia nervosa); trauma-related psychopathology (acute stress disorder, posttraumatic stress disorder, dissociative disorder, resilience); the overlap between psychiatric and other medical disorders (somatoform disorders, medical trauma); personality development across the life span, and sports psychology.
