I am a researcher, former teacher, and policy advisor with nearly two decades of experience spanning classrooms and national education systems. I study how education reforms translate into changes in schools, classrooms, and student learning. My research looks beyond whether policies and programs work to examine the mechanisms that shape implementation, learning, and sustained change in resource-constrained settings. I use experimental and quasi-experimental methods alongside observational and qualitative research. I partner with ministries of education, international organizations, and NGOs to generate evidence and inform policy and practice. Underlying this work is a belief that education can widen what is possible, especially for children whose futures depend most on whether systems deliver.
