Current Research

My current work is focused on developing new effectiveness monitoring metrics to assess the impact of riparian and stream restoration programs; studying soil-water interactions and their role in regulating the export of carbon and nutrients from coastal temperate rainforest watersheds; developing watershed classification methods to predict the effects of climate change; studying carbon fluxes from coastal temperate rainforest watersheds; and studying the ecology of hyporheic zones and retention and transformation of salmon-derived nutrients in streams.

Research Interests

Stream ecology, nutrient cycling, carbon cycling, riparian-stream interactions, hydrology and ecology of surface-groundwater interaction zones, global warming and its effects on streams and stream habitat, terrestrial-near shore coastal zone interactions, fate of carbon in streams and estuaries, and the functional role of wetlands in watersheds.

Past Research

My past work has focused on microbial ecology, microbial carbon cycling, dissolved organic matter processing and chemistry, stream nutrient cycling, stream trophic ecology, invertebrate feeding ecology, ecology of blackwater rivers, and development of methods to measure aquatic bacteria and biomass.

Why This Research is Important

Understanding the management of aquatic ecosystems and watersheds requires an understanding of the fundamental energy and nutrient cycles and their controls. Human activities and natural disturbances all affect the underlying physical and biological processes within ecosystems in interacting ways. To anticipate and mitigate the long-term impacts of changes on ecosystem structure and function requires a better understanding of how the ecosystem works, what supports biological production, and how a habitat's physical characteristics respond to disturbance.
