I am a research fish biologist at the Columbia River Research Laboratory in Cook, WA. I began working on fisheries studies in 1998 and my research has focused on Pacific salmon and dams in the Pacific Northwest. My expertise includes the use of telemetry systems to monitor juvenile and adult salmon and steelhead, and I am currently working on the Willamette and Yakima rivers.
Research Interests:
My research interests include the evaluation of dam passage and survival, assessment of fish collection devices, development of fish passage options at high-head dams, reintroduction of salmon and steelhead to areas blocked by dams, and effects of climate change on salmon ecology and dam management. I am currently working on studies that evaluate the effects of flow management on juvenile salmon survival, the responses of adult salmon and steelhead to trap-and-haul procedures, assessment of dam-passage survival of juvenile salmon, and developing methods to estimate survival of salmon fry in reservoirs.

Scientific Support of Salmon and Steelhead Reintroductions in Impounded River Basins of the Pacific Northwest
Salmon and steelhead populations in the Pacific Northwest were severely affected by hydropower development that occurred during the first half of the 20th century. Impassable dams were constructed on many rivers throughout the region which prevented returning adult salmonids from accessing important habitats where spawning and rearing historically occurred. In the past two decades resource...Steelhead and Spring Chinook Adult Spawning Migration Study in the Klickitat River (Washington)
Fishery biologists from the U.S. Geological Survey are cooperating with Yakama Nation fishery biologists and technicians to conduct a migration behavior study of returning adult steelhead and spring Chinook using radio telemetry. - News
