I am an Ecosystem Ecologist, with a PhD in Forest Ecology from the Swedish University of Agricultural Sciences.  My training is in aquatic chemistry and biogeochemistry, with a primary focus on carbon and nitrogen transformations and hydrological transport within boreal and temperate watersheds, and a secondary focus putting freshwater carbon cycling processes into the context of landscape and regional scale carbon cycling. I use a combination of field vegetation and soil surveys, lab-based water and soil chemistry/biogeochemistry analysis, empirical modeling and GIS-based modeling to evaluate the relationship between landscape/watershed characteristics and surface water chemistry and biotic communities.
 
My current research projects involve a range of topics which I find interesting and compelling:  climate change and freshwater ecosystem carbon cycling, biogeochemistry of urban aquatic ecosystems, and ecosystem services provided by urban green spaces. I supervise both graduate and undergraduate students here at the University of Cincinnati, and these students are currently pursuing projects mainly related to nutrient runoff and water quality in urban areas. Many of my current projects are centered around quantifying ecosystem services and potential disservices associated with green (vegetated) roofs. Green roofs are known to intercept and reduce runoff during rain events, to reduce the urban heat island effect, and to function as good insulators thus saving heating/cooling energy. But, little is known about the direct biogeochemical functions of green roofs, for example: What capacity do green roofs have for nutrient sequestration during rain events? For greenhouse gas sequestration? Or, do they function as a source of nutrients and greenhouse gases, and if so – how can they be designed to minimize these dis-services? And, what are the key climate, geophysical, and biological factors that control nutrient cycling in these novel urban ecosystems?
