Statement
I am broadly interested in the ecology of aquatic ecosystems, and their interaction with surrounding natural and human altered landscapes. I pursue research questions at many scales and levels of organization, using experimental, comparative and stable isotope approaches. I am particularly excited by interdisciplinary, collaborative research that integrates across multiple spatial and temporal scales.
My current research areas include investigation of energy flow regulation in river food webs, impacts of introduced species on aquatic ecosystems, surface and groundwater interactions in stream carbon and nutrient cycles, and carbon and nitrogen biogeochemistry of boreal and arctic watersheds. A pervasive theme in much of this research is that both food webs and ecosystems interact across traditional boundaries of ecological investigation through fluxes of elements, organic matter, and organisms. I am interested in understanding the nature and controls of such interactions, and their role in regulating the productivity and structure of aquatic and terrestrial ecosystems.
