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 in order to continuously monitor belowground abiotic and biotic processes.

I also designed and am operating a long-term, field-based soil experiment. 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
