Areas of Research
I am a geophysicist with interest in the physics of wave propagation, signal processing, and direct inversion of geophysical data. This research is primarily applied (or at least designed for application) in seismic exploration and reservoir monitoring, but it can also be used in, for instance, imaging and inversion of radar data.
Inverse scattering is the main framework that I use to create methods for modeling, processing, and inverting seismic data. At the more theoretical end of this kind of research I am considering basic, fundamental mathematical and physical issues in developing non-linear inverse scattering methods for waves that attenuate significantly in the subsurface. At the more applied end I am interested in using perturbation methods of this kind to pose time-lapse problems, and to analyse dispersive reflection coefficients in order to characterize fluid-bearing subsurface structures. The latter might be hydrocarbon reservoirs, or CO2 storage sites.
