Dr. Weber-Shirk received his PhD in Environmental Engineering from Cornell University in 1992. His experiences working in Salvadoran refugee camps in Honduras helped shape his interest in sustainable technologies for safe drinking water. In 2005, he founded the AguaClara program to address the need for sustainable municipal scale water treatment in resource poor communities. His investigations of the widespread failure of automated and mechanized water treatment plants have provided the impetus to develop a new approach to solve this global infrastructure problem. He has guided the AguaClara team to invent a series of technologies that together make it possible to produce safe drinking water without using any electricity. He organized the AguaClara program to engage students to conduct research and create a free online water treatment plant design tool. He works to empower partner organizations that in turn empower communities to build, operate, and sustain their AguaClara water treatment plants. His research team is investigating methods to improve performance and reduce the cost of drinking water treatment. He guides students using a combination of peer-based, project-based, and lecture formats.
