Jennifer ("Jenna") Davis' research interests focus on the intersection of economic development and environmental management, with particular emphasis on cost-effective, sustainable water supply and sanitation (W&S) service delivery in developing countries.  Current research projects focus on decentralized, private-sector delivery of W&S services in several countries; sustainable sanitation solutions for middle- and low-income urban areas; synergies between W&S planning and economic development strategies (e.g., agricultural productivity); and links between water, sanitation, and health.  She has conducted fieldwork in more than a dozen countries, including most recently the Philippines, Mozambique, and Bolivia.
