Research Areas

Hydrogeology and fluid flow; marine geology; and sediment mechanics

Research Statement

My research focus is on the hydrodynamics of the shallow crust (0-5 km). Through observation, theory, and experimentation, I study the interaction of subsurface flow, sediment deformation, and slope failure. I am particularly interested in how physical properties (e.g., porosity, permeability, compressibility) vary in response to stress perturbations and fluid content (water and hydrocarbon), and how these properties influence sediment strength. It is important to understand these processes to describe fluid/sediment dynamics in the shallow subsurface, to define the conditions of sediments that are eventually buried deeper, and to understand the nature of sediments involved in submarine slope failures. The results are applicable to understanding the hydrodynamic processes in accretionary prisms, gas hydrate provinces, and terrestrial environments.

I use numerical models to describe interaction of geology and fluids as basins and flow systems evolve. Currently I am using models to understand the generation of overpressure, fluid flow processes, and sediment stability along passive continental margins. The research documents that passive margins are active and exciting centers for coupled geological processes such as faulting, slope failure, and shallow hydrogeologic flow systems.

At the experimental level, my research is two-tiered. I perform deformation experiments on natural and reconstituted samples to evaluate in situ conditions and physical behavior of sediments over a wide range of stresses and temperatures. I characterize the effects of mineralogy, grain size, fluid content, and phase changes (e.g. free gas becoming gas hydrate) on poro-elastic and flow behaviors of porous media. I also hope to develop scaled experimental sedimentation models to observe active fluid flow and deformation processes. These models will provide a rare opportunity to observe and measure phenomena that often are not observed in nature, such as the conditions just prior to a submarine slope failure.
