Modern Soil Observations and Field-Based Experiments
I study modern soils in order to understand their role in the global carbon cycle as well as to develop new and refine existing paleosol proxies. In particular I make high-precision, field-based measurements of soil O2 and CO2 in order to continuously monitor belowground abiotic and biotic processes.
I also design and operating long-term, field-based soil experiments . I am reproducing the field observations in a soil physics/chemistry model in order to expand the experiment temporally in a simulated environment.
Active Projects include:
1) Developing a process-based understanding of soil carbonate formation
2) Continuous, field-based monitoring of soil O2 and CO2 concentrations to understand soil microbial metabolisms
3) Quantifying the carbonate formation in South African soils via the oxalate-carbonate pathway
