We are ecosystem ecologists studying biogeochemical cycles and linkages between physical, chemical and biological structure and function in aquatic habitats. 

Our research falls into 4 categories:  

1. the spatial and temporal patterns of nitrogen fixation and denitrification in aquatic habitats
2. stream-watershed-lake interactions in the Great Lakes 
3. consequences of restoration for stream and lake ecosystem processes
4. ecosystem perspectives on community interactions and resource subsidies
