Dr. Grands' research has focused on seismically imaging the mantle of the earth. This has included an effort to develop a three-dimensional image of shear velocity throughout the mantle of the earth. The ultimate goal of this effort is to determine the dynamics of flow in the mantle. Dr. Grand has also been involved in several regional seismic studies including studies of the Kurile subduction zone, the India-Tibet collision zone, the East Pacific Rise, and the Colorado Rocky Mountains. Recently he has been involved in a passive seismic deployment across the Rio Grande Rift and Colorado Plateau.

Areas of Expertise

For my PhD work, I use multi-component seismic data to understand the angle dependent reflectivity of different pure and converted Shear-wave modes and its linkage to subsurface fractures and their properties. My research also includes extracting and analyzing direct S-wave modes like S-S and Sv-P generated by conventional P-wave sources to testing their feasibility as a viable S-wave data that provide a low cost alternative to shear wave seismic acquisition surveys. Previously, I have been worked in different roles as exploration, development, production, and research geophysicist for both integrated and independent oil and gas companies. Some of the key projects I delivered include: 2D/3D structural interpretation, velocity modeling, AVO, rock & fluid physics, 4D seismic interpretation, pressure and saturation decoupling, multi-component seismic analysis, seismic inversion, characterization of clastic and carbonate sedimentary systems, sequence stratigraphic analysis, play analysis, and petroleum systems analyses.
