Research

My research focuses on developing wavefield seismic imaging methods applicable to complex geologic structures. Wave propagation in such models is characterized by complex multi-pathing and illumination, as illustrated in this movie.

(See the animations page for more movies.)

Here are links to brief descriptions of some of my recent research projects:

• Micro-earthquake location using sparse data.
• Interferometric imaging condition.
  Statistical stability in random media.
  Random Sigsbee sediments. Random Sigsbee salt.
• Extended imaging conditions.
• Wave-equation migration velocity analysis.
  Wave-equation MVA sensitivity kernels (wavepaths).
  Wave-equation MVA applied to focusing velocity analysis.
• Riemannian wavefield extrapolation.
• Angle-domain imaging.
• Residual migration and linearized image perturbations.
• Huygens wavefront tracing
