Research Interests
Time-dependent brittle creep in rocks plays a key role in the deformation of earth's crust. I am interested in rock mechanics, and my current work involves investigating the effect of pore fluid pressure on creep in sandstones using conventional triaxial deformation devices. Understanding fluid-rock interaction and how time-dependent deformation changes in response to pore fluid pressure would allow for a better understanding of earthquake precursors.
