My scientific interests cover computational aspects of inverse problems and geostatistics, and a wide range of geophysics disciplines including seismology, geothermal investigations, and geomagnetism. My work includes basic as well as applied research, such as planetary seismology, deep seismic studies of the lithosphere, resources exploration seismology, geomagnetic investigations, and thermal studies in boreholes in the Greenland ice shelf. My main contributions have been in the development of algorithms for nonlinear inversion.
