Marguerite Marlow is a Senior Researcher with over 13 years of experience in public health research focused on promoting health and wellbeing across the life course. Her work spans early childhood development, early learning and education, adolescent mental health, and caregiver wellbeing, with a particular emphasis on identifying effective, scalable strategies to support children, adolescents, and families in resource-constrained settings.

Marguerite specialises in the development, adaptation, implementation, and evaluation of programmes to improve child and adolescent development and wellbeing. She has more than a decade of experience designing and evaluating interventions for families, caregivers, and children, implemented through community-based, school-based, and digital or remote delivery models. To date, these programmes have been implemented in 12 countries through partnerships with government and non-governmental organisations. She has also provided training and technical support for research and programme implementation in over 12 countries.

Her previous work includes leading a World Health Organization review of screening tools for developmental delay and autism spectrum disorders in infants and young children, as well as contributing to the development of WHO resources to promote nurturing care through health facilities. She has consulted for UNICEF on adolescent mental health programming and measurement, for WHO on training for child developmental assessments in multi-country research, and for the World Bank Group on parent, caregiver, and community engagement in children’s reading and learning activities for the Read@Home Initiative.
