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.

Geophysics Society to Bestow Highest Honor on Professor
UT Dallas News Center

George McMechan, the Ida M. Green Professor of Geosciences at UT Dallas, has been selected to receive the Maurice Ewing Medal from the Society of Exploration Geophysicists (SEG), the highest honor given by the international organization.
The award recognizes individuals who have made significant contributions to the advancement of the science and profession of exploration geophysics. McMechan will receive the award at the society’s annual meeting in November.
McMechan credited his professional success and research breakthroughs in part to the innovations and efforts of his collaborators and UT Dallas geophysics graduate students, as well as to 30 years of continuing support from corporate sponsors. With more than 35 years of experience in geophysical research in academia, industry and government, McMechan has published more than 260 refereed publications. He is widely known among his peers as an expert in wave field transformations and innovations in data processing technology.
