My research program focuses on community and ecosystem ecology, and I am interested in how organisms and ecosystem processes interact. I ask questions about freshwater food webs, community composition, greenhouse gas production, and ecosystem metabolism. My research relies on field studies, small-scale and whole-ecosystem experiments, and collaborations to scale local observations to global patterns.
Our lab focuses on freshwater community and ecosystem processes. Current research questions include:
What are the drivers of greenhouse gas production and emissions in ponds and lakes?
How do nutrient and carbon loads interact to affect lake community and ecosystem dynamics?
What is a pond? Are ponds just little lakes, or are they functionally distinct?
How are aquatic communities and ecosystems altered by environmental change, such as land use and non-native species?
