Research Interests:
Research interests revolve around the modeling of some geomechanical processes, such as hydraulic fracturing, drilling, rock-cutting and indentation; and on the mechanics of fluid-infiltrated geomaterials. Recent efforts on the modeling of hydraulic fractures have focused on: (1) the analysis of the singular behavior near the tip of an advancing fluid-driven fracture; (2) the study of poroelastic effects, caused by leak-off of the fracturing fluid in the permeable rock; and (3) the analysis of the initiation of hydraulic fractures at a borehole to improve the interpretation of the in-situ stress from a hydraulic fracturing stress test.
Current research on the cutting and indentation of rocks centers on analyzing the different modes of energy dissipation in these processes. The research aims at determining the conditions under which the mode of rock failure induced by the movement of a cutter or an indenter is "plastic" (crushing of the rock), "brittle"; (tensile fracture propagation), or "mixed".
