I am a fish biologist at the CRRL in Cook, Washington.  I joined the USGS in 2000, and my research has focused on Pacific salmon and dams in the Pacific Northwest.  My expertise includes the use of imaging sonar systems to monitor abundances and behaviors of juvenile and adult fish near collection and passage sites, and I am currently working on the Clackamas, Willamette, and Sacramento rivers.



M.S. 2000. Biological Sciences, Eastern Illinois University, IL

B.A. 1997. Zoology, Eastern Illinois University, IL


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 predation and behavioral studies near entrances to fish collection structures.  I am currently working on studies that evaluate the effects of tidal cycles on juvenile salmon and native fish survival, assessment of dam-passage survival of juvenile salmon, and developing methods to automate imaging sonar data processing.
