Ed Kolodziej began his academic studies with a B.S. in Chemical Engineering from the Johns Hopkins University (1998), after which he focused on environmental issues and went to the University of California at Berkeley where he received his M.S. (1999) and Ph.D. (2004) in Environmental Engineering. He came to the UW in 2014 as part of the UW Freshwater Sciences Initiative, with a joint appointment with the School of Interdisciplinary Arts and Sciences (UW Tacoma) and Department of Civil and Environmental Engineering (UW Seattle). As a principal investigator of the The Center for Urban Waters, Ed works at the intersection of water, chemicals, and fish.

Scholarly Interests

Ed’s expertise is using environmental mass spectrometry to assess water quality and contaminant fate in natural and engineered systems, especially focusing on interdisciplinary approaches to complex environmental issues affecting water and ecosystem health. His research group works to characterize and control non-point source pollution, evaluate attenuation mechanisms in natural systems, and optimize engineered systems for trace contaminant removal. With his research group and collaborators, Ed discovered the ubiquitous and toxic pollutant 6PPD-quinone and this team continues to define the composition of roadway runoff and chemical pollution from vehicle tires. His research has been published in Science and featured in news media such as The New York Times, Nature, Scientific American, U.S. News and World Report, and CNN, along with podcast and film media among others.
