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 via email.

Vice President

Stacey Harper

Oregon State University

Stacey Harper is an Associate Professor of Nanotoxicology in a joint position between the Department of Environmental & Molecular Toxicology and the School of Chemical, Biological & Environmental

Engineering at Oregon State University (OSU). In her current research, she uses rapid assays with whole organisms and communities of organisms to evaluate the biological activity and toxic potential of

diverse nanomaterials, including nanoplastics. Last March, Dr. Harper was highlighted as one of the Women in Nanotechnology by the National Nanotechnology Coordination Office for Women’s History

Month. She will present “Integrative nanotoxicology: linking rapid assays and informatics to understand nanomaterial-biological interactions”.



Bob Johnston

Applied Ecological Solutions

Dr. Bob Johnston is a retired civil servant who worked as a senior scientist at the Space and Naval Warfare Systems Center Pacific, where he coordinated environmental studies for the Navy.  Dr. Johnston has been involved with SETAC since 1989 and serving on the PNW-SETAC board is an opportunity to pay back to the Society.  During his career, he served as project officer and principal investigator to develop methods for conducting ecological risk assessments at Navy sites, investigated the ecological risk of PCBs released from sunken ships in the deep ocean, evaluated the ecological risk of constructing artificial reefs with ex-warships, and he was a coinvestigator in a partnership to model the marine environmental of the Puget Sound, WA.  He also served as Technical Coordinator of a collaborative partnership formed through an ENVivronment inVEStment (ENVVEST) partnership among the Puget Sound Naval Shipyard, Washington State Department of Ecology, U.S. EPA, and local stakeholders to conduct a comprehensive water quality improvement project for the watersheds of Sinclair and Dyes Inlets in the Puget Sound.  In 2007, he was appointed as a charter member to the Puget Sound Partnership Science Panel, created to provide independent, nonrepresentational scientific advice to the Puget Sound Partnership on ecological and human health issues for the Puget Sound, where he served for two terms from 2007- 2013.  Currently, Dr. Johnston is the owner of Applied Ecological Solutions, a small business dedicated to solving environmental problems for discerning clients.


Communications Coordinator

Kaley Major

Oregon Department of Environmental Quality

Kaley Major is a Water Quality Standards Specialist at the Oregon Department of Environmental Quality.  She holds degrees in biology (BS) and environmental science (MS, PhD).  Her most recent research focused on the genetic and epigenetic changes that occur in nontarget populations as a result of exposure to pesticides and/or other chemicals of emerging concern. Now, she works as OR DEQ's toxics point person in water quality standards. When she’s not working, Kaley enjoys making soap, being outside, and learning about all of the amazing varieties of mushrooms in the Pacific Northwest.  She does not miss the winter in Boston, where she received her PhD, and cannot wait to explore more of the Pacific Northwest.

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.
