Main research interests

In the era of the genome and the brain the influence of parenting on child development is not self-evident anymore. In our research programme we examine the role of parents and other caregivers in children's development of attachment and emotion regulation, and we study the limits of their influence. How crucial are parents and other caregivers in shaping their children’s development, not only in relatively regular settings and circumstances but also in extreme situations of family violence, institutional neglect or social upheaval? What influence do children in their turn have on their parents and caregivers, and in what ways do they trigger specific parental interactions, and help build a relationship?
