My research focuses on development and psychopathology. I am especially interested in the ways that individuals become vulnerable to psychopathology early in development. Recent research has addressed 1) the impact of trauma on development, including the developmental antecedents and consequences of attachment disorganization, 2) the interrelationship of socioemotional and representational experience in normative development and in the evolution of disorder (i.e., borderline and dissociative symptoms), and 3) representational models of the self and disorder. Future research directions include the impact of early trauma and stress on physical health across the life span.
