Kenneth Ham came to the PNNL and joined the Ecology Group in 2000. Dr. Ham’s work has concentrated on applying acoustic telemetry and hydroacoustic sonar tools to evaluate fish passage and survival to inform the operation and configuration of the Columbia and Snake River. His research projects also include supporting multi-stakeholder decision processes, developing software to extract information from split- and multi-beam sonar systems, developing interactive visualizations, and developing schema for energy metering data analyses. He directs the development of software tools to process and analyze fish movements in relation to dams and marine hydrokinetic facilities. These tools are used to ensure the development and operation of hydroelectric power meets its goals for stewardship of the environment.
