Current Research
- I lead the Radiocarbon Collaborative, a collaboration-based research initiative sponsored by the Northern Research Station. The Radiocarbon Collaborative expands Forest Service researcher access to radiocarbon analysis, with the goal of assisting researchers in creating statistically robust radiocarbon datasets which address climate change and terrestrial carbon cycling science. Please feel free to contact me if you are interested in applying radiocarbon analysis to your research.
- Additionally, I participate in soil organic matter research with a focus on mechanisms of organic matter stabilization and mineralogy.
Research Interests
The response of the soil organic matter pool to climate change is currently the largest uncertainty in global C cycle models. My research is focused on elucidating the molecular-to-field scale mechanisms of organic C stabilization in soils, with the goal of improving our ability to predict soil C vulnerability to climate change and discovering methods of managing our soils to preserve soil C stocks.

Why This Research is Important
Radiocarbon dating is a unique and powerful tool for the analysis of ecosystem processes. Incorporation of radiocarbon analyses into a broader range of controlled experiments and field studies stands to vastly improve both our understanding of C cycling processes in ecosystems and the response of those ecosystems to changes in climate conditions.
