My research combines soil and groundwater biogeochemistry and geophysics in order to non-invasively monitor subsurface reactive processes (e.g. organic carbon degradation, microbial dynamics, and mineral precipitation/dissolution). Using geophysical techniques provides in situ information at high spatial and temporal resolution offering a comparatively inexpensive alternative to comprehensively characterize reactive processes.
- Non-target geophysical monitoring of soil reactive hotspots in fluctuating water table environments
- Reactive transport modeling of carbon degradation and coupled elemental cycling (O, Fe, S) in the soil vadose zone
- Coupling reactive transport modeling with geophysical datasets to establish direct links between specific reactive processes and geophysical signal variations
- Using spectral induced polarization as a means to monitor microbial dynamics in porous media
