Areas of Interest

Seismic interpretation, Seismic Attributes, Rock physics modeling for hydrocarbon detection, Source rock identification, Gas hydrates rock modeling, Clastic-carbonate interfaces as petroleum reservoirs, Surface wave tomography using partitioned waveform inversion, Teleseismic tomography, Ambient noise tomography


My research interests focus primarily on combining a range of techniques across the disciplines of geophysics, petrophysics, and geology to further improve our understanding of the subsurface through seismic interpretation.  My research works to refine and employ a wide range of interpretation tools and workflows from multiattribute seismic analysis, geostatistics, machine learning, and seismic geomorphology to rock physics modeling.  I am currently working on a variety of projects including improving the seismic identification of gas hydrate zones in the subsurface, as well as techniques to improve reservoir characterization and prediction on the sub-seismic scale, and seismic tomography.
