Geophysical Studies of Natural Hazards, Natural Resources, and Groundwater, Structure and Evolution of the Lithosphere from basins to the upper mantle, Geoinformatics and Data Integration

My research and teaching interests stress geophysical applications that span a variety of techniques and scales. My students and I have conducted many studies of the structure and evolution of basins and deeper features in the lithosphere around the world using seismic, gravity, and magnetic measurements integrated with geological data. I have also regularly used geophysical methods to study issues such as groundwater resources, earthquake hazards, and characterization of sites for sensitive facilities. Also, I have been very involved in the Geoinformatics initiative and am interested in the development of geophysical databases, techniques that foster data integration, software tools, and Web services.
