I combine plant ecophysiological methods with biogeochemical techniques to explore how critical elements, such as nitrogen and carbon, are cycled within plant rhizospheres. My PhD research focused on dynamic cycling of nitrogen by a deep forest rhizosphere in weathered bedrock at the Eel River Critical Zone Observatory. Now, as a postdoc in the Belowground Biogeochemistry SFA, I study the impact of changing soil redox conditions on the stability of carbon in grassland ecosystems in response to soil warming and water table dynamics. I combine in situ measurements of soil redox potential with characterization of dissolved organic carbon compounds (e.g., TIC/TOC, electron emission MS, FTICR-MS) and redox-sensitive cations (cation/anion analysis) in both the rhizosphere and deeper subsoils to understand how carbon quantity and composition change throughout the soil profile under changing conditions. Using field- and lab-based experiments in combination with long-term observational studies, my goal is to develop a better understanding of the role of rhizospheres in carbon and nitrogen cycling in a changing world.
