Mary Dozier is Unidel Amy E. duPont Chair and Professor of Psychological and Brain Sciences at the University of Delaware in the United States. She has studied the development of young children in foster care and young children living with neglecting birth parents over the last 30 years, examining challenges in attachment and regulatory capabilities. Along with her graduate students and research team, she developed an intervention, Attachment and Biobehavioral Catch-up (ABC), for parents of vulnerable infants. Through randomized clinical trials, ABC has been demonstrated to be effective in enhancing parental sensitivity and children’s behavioral and biological functioning. In 2016 she was named the Francis Alison Professor, the university’s highest faculty honor. In 2018 she received the International Society for Infancy Studies Translational Research Aware and was the 2019 recipient of the American Psychological Association Urie Bronfenbrenner Award for Lifetime Contribution in Developmental Psychology in the Service of Science and Society.
