Frank H.T. Rhodes Professor of Environmental Science
I am an ecosystem ecologist, studying how carbon, water, and nutrients - especially nitrogen - cycle through forest ecosystems and affect processes such as forest carbon storage and catchment retention of nitrogen. I also examine how these processes are impacted by a range of human activities, including air pollution, climate change, and land-use change. Tools include whole-ecosystem experiments, stable isotopes, and ecosystem and global models. I also direct Cornell’s multi-departmental Graduate Program in Cross-Scale Biogeochemistry and Climate (http://www.eeb.cornell.edu/igert/), supported by NSF-IGERT and Cornell’s Atkinson Center for a Sustainable Future. I teach or co-teach in BioEE 1610 Introduction to Ecology and the Environment, BioEE 4780 Ecosystem Biology and Global Change, and BioEE 6680 Principles of Biogeochemistry.

My research centers on understanding the effects of human activities on forest ecosystems, as well as the role of forests in sustaining clean water and regulating atmospheric greenhouse gases. I study processes that affect forest cycling and storage of carbon and nitrogen, focusing on how these cycles interact and respond to human-driven changes in climate, land use, and atmospheric chemistry, with particular emphasis on the response of ecosystems to atmospheric deposition of N from air pollution. Nitrogen emitted through fossil fuel combustion and agricultural activities eventually deposits onto downwind ecosystems: much of the work in my lab focuses on understanding the mechanisms by which ecosystems retain or remove these elevated N inputs, and the consequences of these N inputs on ecosystem processes. These consequences include acidification of soils and streams, shifts in species composition, changes in the rates of growth and decomposition, and production of smog and multiple greenhouse gases that have large effects on future climate. Working with a range of collaborators, my lab group uses a range of tools to address many of these processes, at scales ranging from microbial decomposition in soil cores, to plot-scale measurements of isotopic tracers, to whole-catchment recovery from acid rain, to modeled dynamics of N effects on regional carbon storage and the earth climate system.
