My interests center primarily involve the integration of geologic information with quantitative tools for seismic reservoir characterization. This area of research includes both forward and inverse problems, which combine rock physics, stochastic geologic modeling, seismic inversion, and wave-propagation modeling. Importantly, we work with and integrate data at scales from high resolution images of rock samples (sub-micron scale) to the surface seismic scale (tens of meters). Across these scales, we develop effective medium models and numerical techniques to model and invert for elastic properties with the ultimate goal of obtaining heterogeneous and anisotropic rock properties.

Areas of Expertise

Exploration Geophysics, in particular rock physics applications and seismic inversion techniques for reservoir characterization.

My current research interests focus on bridging the gap between rock physics (small scale) and large scale seismic attributes. This problem of scale necessitates an integrated understanding of rock physics models (i.e. both isotropic and anisotropic) and their affects on seismic wave propagation. In broader terms, my research hinges on forward and inverse modeling between subsurface rock properties and surface-seismic measurements (i.e. related to acoustic properties of the subsurface). This area of study applies to petroleum systems, hydrogeologic settings, CO2 sequestration efforts, and other fields of active interest.
