Current Research and Scholarly Interests


I study fluid and solid mechanics in porous media at the intersection of energy, water, and the environment. The scientific focus of my research is to understand and develop capabilities to predict and control multiphase flow and mechanical deformation in porous media at the microscale and to translate such knowledge into macroscopic descriptions useful for solving engineering problems.

Specific focus areas are:

1 - Multiscale algorithms for rapid simulation of microscale fluid and solid mechanics to enable characterization of material properties, optimization of flow or geometry, and uncertainty quantification.

2 - Pore network modes and hybrid computing for reliable prediction of solute transport and geochemical alterations in porous media.

3 - Multiresolution imaging and data integration to map petrophysical properties of geomaterials at sub-millimeter resolution over the meter scale.

Motivating application areas are:

1 - Geologic carbon storage
2 - Geothermal energy
3 - Hydrocarbon recovery
4 - Groundwater remediation
5 - Fuel cells & batteries
