I use an interdisciplinary approach to understand the complex engineered, environmental, and human systems that enable the provision of safe, reliable, and sustainable drinking water. My core expertise is in civil systems engineering, where I use a mixed-methods approach to combine engineering problem solving tools with methodological training in the disciplines of public health and social sciences. I have conducted extensive field work in India and throughout Africa. My research addresses the scientific, engineering, and policy challenges in building and maintaining adaptable and resilient water systems to meet human and environmental needs into the future. To that end, my research focus is centered in three main areas: 1) Safe and sufficient water in a rapidly urbanizing world; 2) Global and local progress in access to safe water; and 3) Information and communication technologies that improve water and sanitation services.

Intermittent to continuous piped water supply

In 2010, we set up a study to evaluate the conversation from intermittent piped water supply to continuous supply (’24×7′) in Hubli-Dharwad, India, where 10% of the population was switched to 24×7 supply and the remaining residents accessed piped water intermittently. We studied the impacts of this conversion on water quality, health, and household economics. This also provided us an opportunity to study features of an intermittent supply, including the mechanisms leading to contamination in these systems and the quantities of water consumed by households with unreliable water delivery.
