Post Masters Research Associate – Waterpower Science & Ecology

Richland, WA · Full Time

Job Details

Be part of a large interdisciplinary team researching the effects of hydropower operations on the passage, survival, and injury of juvenile salmon and lamprey across the Columbia, Snake, Willamette, and other river systems in the Pacific Northwest. Research activities include deploying, retrieving, maintaining, and testing acoustic and radio telemetry equipment; tagging fish or assisting with surgical implantation of transmitters; and transporting and releasing live, tagged fish according to detailed schedules.

Project responsibilities include fieldwork, data collection, data analysis, and report writing. Seasonal fieldwork may require frequent regional travel. The successful candidate may also support laboratory studies involving fish handling, maintaining fish populations in aquaculture facilities, and conducting detailed necropsies.

In addition, the position may involve conducting comprehensive fish injury assessments on specimens that have undergone turbine passage (simulated or actual) or transit through other water infrastructure facilities. These assessments include documenting internal and external injuries through established necropsy protocols to ensure accuracy and ethical handling. The role may also require analysis of high-resolution imagery to support precise injury quantification and contribute to data collection and model training for AI-based Fish Assessment tools aimed at improving predictive analytics and mitigation strategies in aquatic environments.
