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 more than 20 academic, non-profit, and private industry partners around the world to facilitate the development and sustainable deployment of novel technology-based solutions for health and environmental challenges.

Our research ranges from the design, engineering and field testing of decentralized 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:

  • Leverage 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 empower women and girls with gender transformative solutions
