Janna Metzler, DrPH, MPH, MSW, focuses on developing an evidence base for children's programming in humanitarian settings. Dr. Metzler's particular areas of expertise include conducting participatory research with children and adolescents, understanding and promoting healthy developmental pathways for children in emergencies, and the evaluation of child- and adolescent-focused interventions. An expert on measurement and evaluative approaches for children's programming in emergencies, she has provided design, monitoring and evaluation technical support to field teams globally. Dr. Metzler presently leads the implementation of a randomized controlled trial of an enhanced model of Child Friendly Spaces within Columbia University. She also oversees research examining the prevalence and drivers of child marriage in nine humanitarian settings and research related to adolescent sexual and reproductive health in emergencies more broadly at the Women's Refugee Commission.
