Current research emphasizes seismology
and ground-penetrating radar.
In seismology, projects include
development of software for numerical simulation of scalar, acoustic,
elastic, viscoelastic, and poroelastic isotropic and anisotropic
responses, and the corresponding inversion, imaging and migration
processes. Applications include reservoir and aquifer
characterization, AVO, cross-well and VSP, earthquake source studies,
3-D, multicomponent and wide-aperture analyses.
ground penetrating radar, projects include development of software for
numerical simulation of dielectric and moderately conducting
materials in 2-D, 2.5-D and 3-D, and the corresponding inverse
problems. Applications include 3-D characterization of reservoir
analogs, sedimentological mapping, earthquake fault mapping, and
engineering and environmental problems. Projects include experiment
design and data acquisition, as well as processing and interpretation.
