Dr. Davis  is an Associate Professor in the Department of Civil and Environmental Engineering and the Higgins-Magid Senior Fellow at the Woods Institute for the Environment. Dr. Davis's research and teaching is focused at the interface of engineered water supply and sanitation systems and their users in developing countries. With a background in public health, infrastructure planning, and environmental science and engineering, Dr. Davis explores questions related to interventions that trigger household investment in water, sanitation, and hygiene improvements; the features of water and sanitation services that users value and why; and the health and economic impacts of improvements in water supply and sanitation. She has conducted field research in more than a dozen countries, including most recently Kenya, Mozambique, and Bangladesh. Over the past five years, approximately 25 graduate students and post-docs have obtained training in the field with Davis's projects.
