Research Interests>>
- My research focuses on developing the geophysical method nuclear magnetic resonance (NMR) as a method to monitor in situ contaminant remediation. There is a need to develop such methods as current methods to monitor subsurface contaminant remediation rely on direct sampling, which can be costly and incurs the risk of further spreading the contaminant.
NMR is a measurement technique that is widely used in medical imaging and chemical analysis and has also been applied in geophysics in the laboratory and the field. Currently in geophysics these measurements are used to determine subsurface water and hydrocarbon content as well as estimate pore-scale properties of geologic materials. However, the NMR response is also sensitive to the chemical and magnetic properties of the geological materials in which the water or hydrocarbon is contained. This sensitivity means that the NMR measurement is sensitive chemical changes in subsurface minerals and thus could be used to monitor in situ contaminant remediation. My research uses laboratory measurements, numerical modeling, and field studies to understand the link between the chemical and magnetic properties of geologic materials and the NMR measurement.
