Description

Or Dagan, Ph.D., is an Assistant Professor in the Clinical Psychology Doctoral Program at LIU Post. Dr. Dagan received Ph.D. in Clinical Psychology from the New School for Social Research and completed multiple research postdoctoral fellowship at Stony Brook University, Vrije Universiteit Amsterdam, and New York University- Abu Dhabi. Dr. Dagan is a member of the editorial board of the scientific journals Attachment & Human Development and the Journal of Family Psychology (starting 2025). His research program focuses on the links between attachment behaviors (e.g., expressing a need for support and proximity seeking) and representations (i.e., the way remember our past interactions with our caregivers) and mental health across the lifespan. Specifically, he is currently involved in programmatic research assessing (a) early attachment network to multiple caregivers as a predictor of socioemotional and cognitive outcomes, (b) the role of scripted attachment representations in predicting mental health and romantic relationship quality in adolescents and adults, and (c) attachment behaviors between romantic partners under conditions of mild distress. Through his educational, research and practice platforms, Dr. Dagan is committed to promoting sensitive communication between people and within families, which stands at the heart of well-being.

Specialties

Attachment Theory, research, and interventions; Developmental Psychopathology; Psychodynamic and Relational Psychotherapy.
