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 transport processes in porous materials at the micron/nano scale and to translate such fundamental knowledge into large-scale mathematical descriptions useful for analyzing engineering problems.

My approach focuses on:

1 - Developing computational methods and advanced algorithms for accelerated simulation of fluid dynamics and solid mechanics at the micro scale so as to enable characterization of material properties (e.g., permeability, capillary pressure), optimization of design and operational controls in geologic (rocks/soil) and synthetic (fuel-cell/battery) porous media, and quantification of uncertainty

2 - Devising mathematical and computational methods to upscale microscopic predictions to large-scale engineering systems (core/field)

3 - Developing experimental techniques for characterizing hydro-thermo-mechanical properties of geologic porous media (e.g., shales) at high-resolution through a combination of meter-scale hyperspectral imaging and microscopy

Application areas that interest me include:

1 - geologic carbon storage
2 - hydrocarbon recovery
3 - geothermal energy
4 - subsurface hydrology
5 - fuel cells & batteries
