Scientist, water, team in the field

Duke University Center for Water, Sanitation, Hygiene and Infectious Disease

The Duke University Center for Water, Sanitation, Hygiene and Infectious Disease (WaSH-AID) is a collaborative translational research team working closely with academic, non-profit and private industry partners around the world to facilitate the development and sustainable deployment of novel technology-based solutions for critical health and environmental challenges.

Our research ranges from the design, engineering, and field testing of onsite waste treatment technologies to the exploration of sensors, diagnostics, and machine learning to detect pre-symptomatic disease at the individual and community level. 

To achieve our mission, we

  • Emphasize cross-disciplinary expertise and partnerships.
  • Work along a continuum from basic and translational science to prototyping, field testing, and commercialization.
  • Embrace a user-centered philosophy in all stages of research and development.
  • Seek to promote equity and justice with inclusive and transformative solutions.

Smartwatches Track Our Health. Smart Toilets aren't too far behind.

The next frontier of at-home health tracking is flush with data: the toilet. Researchers and companies are developing high-tech toilets that go beyond adding smart speakers or a heated seat. These smart facilities are designed to look out for signs of gastrointestinal disease, monitor blood pressure or tell you that you need to eat more fish, all from the comfort of your personal throne.
