Research Summary
I study rock deformation and fluid flow through porous-fractured rocks from the scale of laboratory samples to that of hundreds of meters sized reservoirs, using experimental and field methods. My current project aims to quantify the effect of true triaxial states of stress in the elastic and fluid flow properties of rocks.听
