Professor Daniel Giammar completed his B.S. at Carnegie Mellon University, MS and PhD at Caltech, and postdoctoral training at Princeton University before joining Washington University in St. Louis in 2002. His 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. 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 received a National Science Foundation Faculty Early Career Development (CAREER) Award in 2006. He has active collaborations with faculty in Earth and Planetary Science, Chemistry, and Social Work that enable interdisciplinary investigations of important environmental systems. Professor Giammar is currently an Associate Editor of Environmental Science & Technology and a member of the Journal Editorial Board of Journal American Water Works Association. In 2012-2013 he was a visiting professor at Princeton, and he visited the University of Vienna in 2007 as a guest professor. Professor Giammar has enjoyed other international collaborations with colleagues in India and China.
