I am interested in the geophysical study of the crust and upper mantle of the Earth and its relation to tectonic deformation. My ongoing projects include work in New Zealand, Alaska, and the Rocky Mountains and Rio Grande Rift and of Colorado and New Mexico. Much of the work I do includes the deployment of portable seismometers both on-land and in oceanic regions (ocean bottom seismometers). The seismometers record both distant and local earthquakes. The earthquakes are used as signals to image subsurface structure and to study earthquake source characteristics. I have been involved with recent experiments that use ocean bottom seismometers offshore New Zealand and Alaska. I am interested in earthquakes in the Rocky Mountain region, both tectonic and induced by human activities. My work in the Rocky Mountain region includes the use of electromagnetic methods (magnetotellurics) and GPS geodesy experiments in addition to seismology.
