    Research Areas
     Seismology and inverse methods.
     
    Research Statement
     My research interests include the development and application of seismic modeling and inversion techniques in tectonic, exploration and environmental studies of the lithosphere, sedimentary basins, and shallow targets. Study areas throughout the world encompass most types of continental plate tectonic settings: shields, platforms, young orogenic belts, passive margins, active/recent extension, and convergent margins.

    I develop models of the seismic properties of the Earth's subsurface in 2-D and 3-D using artificial sources, and reciever arrays that are from tens of meters to a few hundred kilometers long, both on land and at sea. In most cases this involves the interpretation of wide-angle seismic refraction/reflection data for P-wave velocity structure. I interpret these models along with existing information which may include surface geology, well data, and results from seismic reflection, earthquake, magnetotelluric, gravity, magnetic, and geothermal studies.

    To suit a particular set of data or geologic target, I develop forward and inverse seismic modeling techniques. I am also involved in acquiring land and marine seismic data with colleagues at Rice and other institutions.

    Research Statement

     

    My research interests include the development, assessment and application of seismic modeling and inversion techniques for studies of the near-surface (upper 100m), basins and crust. More specifically, this includes 2D and 3D traveltime inversion and tomography methods, including a newly developed frequency-dependent form of tomography that is applicable to controlled-source (picked) traveltime data. My students and I are also applying 2D full waveform tomography methods for P-wave and S-wave data.


     


    We develop models of the seismic properties of the subsurface in two- and three-dimensions using artificial sources, and receiver arrays that are a few tens of meters to a few hundred kilometers long, both on land and at sea. In most cases this involves the interpretation of seismic refraction/wide-angle reflection data. We often interpret these models along with existing information that may include surface geology, well data, or results from seismic reflection, earthquake or gravity studies. Recently, my focus has turned to the shallow subsurface (upper tens of meters) for environmental, engineering and risk assessment studies.


     


    I sometimes get involved in acquiring land and marine seismic data with colleagues at Rice and at other academic and government institutions. I also study methodological aspects of traveltime and waveform tomography and inversion. Finally, I am also interested in, and teach an introductory course in, geophysical inverse theory.
