Current Research
My research focuses on biogeochemical cycling with an emphasis on linkages between terrestrial and aquatic ecosystems. My past work has primarily involved cycles of nitrogen and carbon, but also includes the cycles of other elements. The research has been conducted at multiple spatial scales ranging from plot studies to global syntheses. Current activities include examining how disturbances, such as acidic deposition, affect nutrient cycling in forest ecosystems.
Why is This Important
Forests provide a number of ecosystem functions and services, and it is critical to identify the effects of human accelerated environmental change on these valued resources. The overall goal of my research is to provide a more comprehensive understanding of the ecological consequences of human disturbance in the northeastern U.S. that will be used make more informed environmental policy decisions.
Future Research
Future research will include modeling biogeochemical responses to climate change in northeastern North America. I am also interested in how soil frost affects biogeochemical cycling and stream water nitrogen in particular. Lastly, I am planning to use isotopes of water to refine the water budget at the Hubbard Brook Experimental Forest, which will provide a better understanding of hydrological processes at the site.
