    Dr. Miller’s research involves theoretical, computational and experimental aspects of transport phenomena in multi-scale, multiphase environmental systems with special emphasis on porous medium systems. This broad area of inquiry supports advancing understanding for a range of important applications including hydraulic fracturing of subsurface systems, carbon sequestration, land-atmosphere interaction, environmental remediation and engineered systems.

    Dr. Miller and William G. Gray are developers of the thermodynamically constrained averaging theory for formulating mathematical models that are consistent across various length scales and which have application in a wide range of fields including water resources, environmental engineering, biomedical engineering, physics and applied mathematics. Dr. Miller's research group is actively involved in high performance computing to simulate environmental systems.
