Third-year graduate student in the Stanford Rock Physics and Borehole Geophysics Project (SRB) working under the supervision of Gary Mavko and Tiziana Vanorio. Research topics are geared towards understanding the evolution of the rock physics parameters, e.g., porosity, permeability, velocity anisotropy, velocity-sensitivity to pressure, of organic-rich shale as it matures thermally both in situ and in the laboratory. The evolution of rock physics parameters is analyzed through a combination of laboratory methods, high-resolution SEM and CLSM imaging, and digital rock physics simulation (particularly the simulation of the permeability of kerogen bodies). The driving mission of this work is to better identify shale formation properties from seismic attributes, e.g., connect the spatial variation of anisotropy to the kerogen porosity and permeability of the formation, in order to identify 'sweet-spots' for targeted drilling strategies.


Secondary work with the Stress and Crustal Mechanics group, under the supervision of Mark Zoback, aims to characterize the adsorptive properties of several shale formations at representative reservoir temperatures for comparison with previous measurements carried out in the same lab.
