The original goal is to devise computational methods for improving the resolution of subsurface seismic images. Initially the research emphasis was primarily on developing methods for efficient ray- theoretic modeling of acoustic waves in triangulated representations of media and on efficient means of modeling waves that travel sub- horizontally in horizontally layered media. Subsequent directions included new efficient methods for imaging the Earth`s subsurface (specifically, 3-D migration via the McClellan transformation, and squeezing dip movement (DMO) for depth-variable velocity), demonstrations of the importance of taking P-wave anisotrophy into account in migration and DMO, the development of algorithms for doing migration and DMO in heterogeneous, anisotropic media, and the development of a methodology for the all-important step of deriving the anisotrophy parameters necessary for imaging of P-wave data.
