At-Large (Government)

Arthur Buchan
Washington Department of Ecology

I am a Toxics Cleanup Program Toxicologist for the Washington State Department of Ecology, where I work in the Policy and Technical Support Unit.  I am responsible for providing technical assistance for eco-toxicology issues throughout the state, which include site specific recommendations and policy/education.  My professional interests include Wildlife Exposure Modeling, Plant and Soil Bioassays, and Net Environmental Benefit Analysis.  Recently, I have developed guidance for Terrestrial Ecological Evaluations, Dioxins/Furans/PCBs, and am currently working on a Benthic Biomass Endpoint.  Recognizing the importance of the prevention of releases of toxic substances, I also became certified as a Cathodic Protection Technician, which then allows me to provide technical assistance relating to corrosion issues.  On a personal level, I enjoy spending time with my family (wife and two children), fishing, and travel.  I served fours in the Military, have a B.Sc. from Eastern Washington University and a M.Sc. from Central Washington University.  I started working for the Washington State Department of Ecology in 2004, and my office is located in Olympia, WA.         

At-Large (Academia)

Ed Kolodziej
University of Washington

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 University of Washington (Tacoma and Seattle campuses) in 2014 as part of the UW Freshwater Science Initiative after seven years as faculty at the University of Nevada, Reno, in Civil and Environmental Engineering. He currently holds a joint appointment with Interdisciplinary Arts and Sciences at UW Tacoma and Civil and Environmental Engineering (UW Seattle), and is affiliated with local and regional water quality efforts through The Center for Urban Waters (http://www.urbanwaters.org/) in Tacoma, WA.

Ed’s interests include 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, understand attenuation mechanisms in natural systems, and optimize engineered systems for trace contaminant removal. He has extensive experience in trace analytical chemistry for organic pollutants, endocrine disruption and sublethal impacts on aquatic organisms, and the fate of bioactive contaminants in aquatic habitats. Outside of work, Ed can often be found doing something outside, usually rock climbing, skiing, hiking, or fly fishing.


At-Large (Student)
Lauren Crandon
Oregon State University

I am a third year PhD student in Environmental Engineering at Oregon State University.  I became a member of SETAC shortly after moving from Kansas to start my graduate career.  As an undergraduate, I served as an active member of our Engineers Without Borders student chapter and helped organize a volunteer trip to New Orleans to assist in building a more sustainable community after the devastating impacts of Hurricane Katrina.  I became interested in alternative fuels and became part of an interdisciplinary research team focused on every aspect of an alternative liquid fuel, from the cultivation of biomass, its conversion to fuel, and viability in a combustion engine.  This sparked my passion for collaborative and interdisciplinary research.  I currently work as a graduate research in Dr. Stacey Harper’s nanotoxicology lab.  Our mission is to evaluate the environmental health and safety impacts of nanotechnology by incorporating engineering principles and toxicity assessments. 

I am highly motivated by SETAC’s commitment to apply multidisciplinary approaches to solve environmental problems.  I plan to continue my involvement in SETAC as the student representative.  I believe my interest in collaborative research, ability to communicate science as a mentor, and my commitment to community outreach have prepared me to take on this role.
