Research Interests

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.

In 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.
