Helen Elizabeth Davis PhD


Dr. Davis began working with the Tsimane people of Bolivia in 2005, and started working in the Kunene/Cunene region of Namibia/Angola in 2016. Davis began collaborating with Engineers Without Borders in 2009 and Ondao Mobile Schools in 2017. Dr. Davis’ professional work focuses on education and child development, and she has performed extensive research suggesting there is a critical link between the availability of resources during childhood and academic achievement. It was this work that led her to establish One Pencil. Dr. Davis oversees the Bolivia and Namibia chapters and currently works at Harvard University.
