Biography

I am an ecosystem ecologist who studies biogeochemical cycles and linkages between physical, chemical and biological structure and function in watersheds. Linking these often requires understanding the underlying structure of microbial, algal, and animal communities. I am also working to place concepts of food webs into a broader ecosystem context by merging measurements of ecosystem production and food web pathways. Therefore, my research occurs at the interface of ecosystem and community ecology. I enjoy research that is both fundamental and applied, and have explored the interface between academia and management in projects examining the effects of salmon marine-derived nutrients on stream-riparian production and the effects of land use and habitat degradation on nutrient cycling and export from rivers.

One benefit of an academic career is the synergy between an active research program and undergraduate and graduate education. I currently teach undergrad and graduate courses in Limnology and Ecosystem Ecology, as well a professional development seminar for graduate students called The Scientific Profession where we cover topics related to grant writing, publishing, jobs, work-life balance, ethics, and gender issues, among many others.
