Current Research
My research focuses on several issues including the effects of man-made large-wood structures on fish, response of stream biota and channel morphology to dam removal and debris flows, and the development of benthic macroinvertebrate communties in streams and ponds created from the eruption of Mount St. Helens in 1980.
Past Research
My past research has explored the effects of: invasive knotweed management actions on riparian vegetation communties and structure; knotweed leaf decomposition on stream ecology; salmon carcasses and marine-derived-nutrients on stream food webs and productivity; and forest harvesting on temperature, aquatic invertebrates, and riparian mollusk and millipede diversity in and near headwater streams.
Research Interest
  • Riparian and aquatic systems interactions
  • Role of aquatic invertebrates in stream and lake systems
  • Community ecology, disturbance ecology, food webs, and ecological impact of invasive organisms

Research Highlights

River Conditions Improve with a Modified Dam Removal Strategy in Washington State

Year: 2015
Forest Service scientists used a modified dam-removal strategy on the Hemlock Dam in Washington to successfully minimize downstream sedimentation while restoring migratory steelhead access and improving conditions for other aquatic life. The research findings can help watershed managers determine th...

Herbicide Eradication of Invasive Plants May Release Exotic Invaders

Year: 2013
Noxious weed control programs can benefit from including post-treatment plant community surveys to determine if continued management is needed to achieve restoration objectives.
