Pacific Northwest Chapter of the
Society of Environmental Toxicology and Chemistry

Promoting toxicology and chemistry research in the Pacific Northwest

Meet the Board!!

The PNW-SETAC Board is an all-volunteer group of scientists from diverse educational and professional backgrounds.  It is comprised of Officers (Immediate Past President, President, Vice President, Treasurer, and Secretary) and a Board of Directors representing academia, government, and industry.  Officer and Board members are elected by the membership, usually in the fall, and serve 3-year terms.  We also have an At-Large (Student) Board member who is appointed annually by the Board.  Please feel free to contact any of our Officers or Board members by clicking on their titles in their profiles.

Kara Warner has an interdisciplinary background in biology, physiology, and toxicology.  She is a Senior Environmental Scientist with Golder Associates Inc., a global geotechnical and environmental services consulting firm.  Kara’s professional experience includes environmental impact assessment components, ecological and human health risk assessments, water quality, air quality, permitting, and regulatory compliance.  She has worked at Golder for 9 years, and prior to that, Kara held several teaching and research positions, including a post-doctoral position.  She has a Ph.D. in Toxicology from Oregon State University, and an M.S. degree in Biology from Texas State University.  Kara is married with two children, ages 10 and 7, and she enjoys traveling, reading, and golfing.

, Webmaster, and Registered Agent
April Markiewicz treasurer
Western Washington University

April is a Toxicologist II and the Associate Director of the Institute of Environmental Toxicology at Western Washington University (Western).  She is also an adjunct faculty in the Department of Environmental Sciences in Huxley College of the Environment at Western.  She received her B.S. in Fisheries and Wildlife from Michigan State University and M.S. in Aquatic Toxicology/Aquatic Ecology from Western.  April directs, manages, and supervises the day-to-day operations of the Institute.  She also serves as a technical and informational resource for students, staff, faculty and the general public, teaches classes in environmental toxicology, writes grant proposals, and co-authors publications.  Research interests include aquatic and stream ecology with emphasis in ecotoxicological effects on community- and ecosystem-level interactions, as well as chemical partitioning to water and sediments, and its effects on nutrient cycling.


Coreen Hamilton
AXYS Group

Coreen Hamilton is an analytical chemist with Axys in Sidney, BC.  She is a senior scientist, conducts analytical method development for both legacy and pollutants and contaminants of emerging concern and assists clients with all aspects of their projects from designing sampling plans through to data validation.  Her work includes development of methods for the EPA, techniques for high volume sampling projects in the arctic and other remote locations, passive sampling, monitoring pharmaceuticals in wastewater and for naphthenic acids and PAH in northern Alberta.  She is also an adjunct faculty member at the University of Victoria where she teaches general and analytical chemistry.  She received her B.Sc. in Chemistry from McGill University and her PhD from the University of Alberta.  Coreen is also a quilter and avid duplicate bridge player.


Board of Directors

At Large (Industry)
Diana Dishman
NOAA Fisheries/Ocean Associates Inc.

Diana is employed at NOAA Fisheries and Ocean Associates consulting firm.. She has a background in population biology and specializes in quantitative analysis of environmental data and population modeling in support of pesticide risk assessment. Diana also has experience providing support for large-scale natural resource damage assessment (NRDA) studies, generating population models for federal agency conservation planning, conducting food web modeling in support of pesticide registration, and conducting aquatic toxicity testing. She received a B.A. in Organismal Biology from Scripps College, and a M.S. in Biology from Portland State University. When she’s not analyzing data Diana is usually tending the sheep and chickens she raises with her daughter on their two acre hobby farm.

At-Large (Government)

Bryson Finch
Washington Department of Ecology

Bryson Finch is the Water Quality Standards and Hydropower Lead Scientist for the Washington Department of Ecology. He develops and revises water quality standards for conventional pollutants for the State of Washington. He also provides technical assistance on Federal Energy Regulatory Commission related questions, hydropower dam relicensing, and 401 water quality certifications. He also serves as an associate consultant for Compliance Services International for pyrethroid-related water quality issues. Bryson received his B.S. in Environmental Science from Western Washington University, M.S. in Environmental Toxicology from Texas Tech University, and Ph.D. in Toxicology from Oregon State University. On his days off, you’ll usually find Bryson salmon/steelhead fishing, kayaking, hiking, or enjoying time with his family.       

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.
