Researches sustainable solutions to produce safe drinking water


Water quality, aquatic chemistry, and environmental implications of energy technologies


Dan Giammar's research focuses on chemical reactions that affect the fate and transport of heavy metals, radionuclides, and other inorganic constituents in natural and engineered aquatic systems. He is particularly interested in reactions occurring at solid-water interfaces. His recent work investigated the removal of arsenic and chromium from drinking water, control of the corrosion of lead pipes, geologic carbon sequestration, and biogeochemical processes for remediation of uranium-contaminated sites.


Professor Giammar is an environmental engineer with active educational and research programs. He currently teaches courses on environmental engineering and water quality. His current and recent research has been sponsored by the National Science Foundation, Department of Energy, and Water Research Foundation. He has active collaborations with faculty in Earth, Environmental, and Planetary Sciences and in Chemistry that enable interdisciplinary investigations of important environmental systems. Professor Giammar is currently an Associate Editor of Environmental Science & Technology.

Professor Giammar completed his BS at Carnegie Mellon University, MS and PhD at Caltech, and postdoctoral training at Princeton University before joining Washington University in St. Louis in 2002. In 2012-2013 he was a visiting professor at Princeton. Professor Giammar is the McDonnell International Scholars Academy’s Ambassador to Hong Kong University of Science and Technology, and he has enjoyed other international collaborations with colleagues in Austria, India, China, and Turkey. Professor Giammar received a National Science Foundation Faculty Early Career Development (CAREER) Award in 2006. He has also been recognized for his teaching through awards at the university and in the St. Louis region.

Professor Giammar is a registered professional engineer in the State of Missouri.
