My research focuses on the interaction between landscape structure, species assemblages, and biogeochemical cycling in both aquatic and terrestrial ecosystems. While most of my work occurs in streams (lately of which are mostly in Iceland), we have also worked in restored Minnesota prairies.
I am interested in how environmental gradients shape the development of communities and food web dynamics, and the feedbacks between organisms and nutrient cycling. Ultimately, my work aims to link species composition to ecosystem processes in ways that help us better predict the consequences of environmental change (e.g., climate and land use).
This work relies heavily on field-based experimental manipulations of species interactions and resource environments, coupled with landscape-scale surveys, lab and field-based physiological assays, and development of quantitative models.
