Research Methods
Our group combines laboratory experiments, field monitoring, imaging, and numerical modeling to study water, fluids, reactions, and porous media across scales. These methods allow us to connect measurable geophysical signals to subsurface properties such as water content, pore connectivity, permeability, fluid mobility, and reaction progress.
Low-Field Nuclear Magnetic Resonance (NMR)
We use low-field NMR to directly probe water and fluids in porous materials. NMR measurements help quantify water content, pore-size-related relaxation behavior, fluid mobility, and water partitioning in soils, rocks, sediments, and engineered materials.
Spectral Induced Polarization (SIP) and Electrical Methods
Electrical and polarization methods are sensitive to pore connectivity, mineral-fluid interfaces, saturation, and biogeochemical processes. We use these tools to monitor fluid movement, contaminant behavior, and reactive processes in laboratory and field settings.
Digital Rock Physics and Pore-Scale Modeling
We use micro-CT imaging, pore-network models, lattice Boltzmann simulations, and geophysical forward modeling to connect pore-scale structure with macroscopic properties. This helps interpret NMR and electrical signals and predict permeability, connectivity, and transport behavior.
Hydrogeophysical Monitoring and Data Integration
We integrate geophysical observations with hydrological, geochemical, and environmental data to understand complex subsurface systems. This includes laboratory-to-field scaling, time-lapse monitoring, and physics-informed data analysis.
