CRB-CZO Alum: Former Post Doctoral Researcher As part of the Christina River Basin Critical Zone Observatory (CRB-CZO), my study will be focused on understanding the organic carbon – mineral complexation mechanisms. Specifically, the major objective of my investigation is to evaluate in-situ the sensitivity and variability of the mineral surface area in soils with respect to a change of redox conditions (reducing versus oxidizing) across a wide range of landscape positions and uses, such as floodplain forest, upland forest, agriculture and construction areas. The research will a combination of the extensive field and laboratory analyses/experiments coupled with the geochemical reactive transport modeling.
