Current Research:

"Who looks upon a river in a meditative hour, and is not reminded of the flux of all things?" - Ralph Waldo Emerson

Freshwater ecosystems provide invaluable services to society, but are among the most imperiled environments on Earth. My research aims to illuminate the often invisible mechanisms that support freshwater ecosystem productivity and resilience, and use this knowledge to contribute to better-informed stewardship. My research employs holistic, ecosystem-based approaches that combine tools and theory from food-web ecology, ecosystem ecology, and system dynamics modeling.

Current research themes include: (1) synthesizing ecological impacts of dam removal, (2) investigating the influence of landscape complexity on river food webs, (3) quantifying the impact of ecological subsidies on rivers, (4) assessing the impacts of climate change of Pacific salmon, and (5) developing system dynamics models to inform freshwater restoration and management.

Research Interests:

Structure and dynamics of river food webs
Restoration of freshwater ecosystems
System dynamics modeling
Ecology and management of Pacific salmon and trout
Impact of Invasive species on aquatic ecosystems

Past Research:

Much of my past research has focused on river-floodplain ecosystems in the Pacific Northwest and the importance of these floodplains for fish. My dissertation research at Idaho State University illustrated that floodplains support diverse food webs that are important for Pacific salmon and trout. Moreover, this reseach suggested that these complex and interconnected food webs may promote the long-term maintenance of biodiversity by stabalizing ecosystems against perterbations.

Why Is Research Important:

Healthy rivers, streams and lakes directly contribute to human wellbeing. In the Pacific Northwest, for instance, forest streams support valuable commercial, recreational, and subsistence salmon fisheries. By illuminating how these ecosystem's function, my research contributes to informed management and restoration so that these freshwater resources can be enjoyed by future generations
