Research

My research interest is experimental rock and soil mechanics to characterize the hydromechanical properties of rocks and sediments deformed at different pressure, temperature, and strain rate conditions. With the aim of better understanding a wide range of geological problems, I combine lab experimental work with numerical modeling, geophysical data, and field work including ocean/continental drilling projects. Current research focuses on understanding (1) the interaction between sediment/rock deformation and fluid flow under complicated loading conditions associated with earthquakes in subduction zones, and (2) the micromechanics of compaction and shear deformation and on granular materials at high strain rates and high pressures.
