Land-use/land-cover & climatic change effects on biogeochemistry & biodiversity
Mechanisms of soil organic matter stabilization Hydrologic controls on carbon & nutrient transport
Nutrient cycling in terrestrial ecosystems New species assemblages effects on ecosystem structure & function
Restoration of ecosystem goods & services
Human drivers of land-use/land-cover change
My research integrates field and lab experimental work across different scales, from andscape-level effects of changes in land use on species composition and carbon pools, to molecular changes in organic matter chemistry. I use stable and radioisotopes, spectroscopic, and analytical techniques to quantify process rates, identify sources and sinks, and better understand underlying mechanisms controlling stabilization and losses of organic matter and elements within and across ecosystems.

Geography 120: Global Physical Environments
Geography 338: Biogeography: An Ecosystems Approach
Geog 338 takes an ecosystems approach to understand how physical (climate, geology, soils…) and biological (competition, dispersal, migration…) factors affect the distribution of terrestrial biomes, ecosystem types, and biodiversity. Attention will be focused on the relative importance of these factors at different spatial scales: global, regional, landscape, and at the level of communities. Importance will be given to the role of disturbance, and in particular to recent anthropogenic climatic and land-use changes as well as biological invasions, on differences in pre-historical and present day species distribution.
