Earth Surface and Interior

Group Supervisor


Over 25 years experience in earthquake and plate boundary deformation research. Led GPS study of interseismic coupling of the Middle America subduction zone in Costa Rica. Has over 20 years experience applying SAR interferometry to earthquake and volcano source studies. Has extensive experience in integrating seismic waveforms and geophysical observations through inverse and forward numerical models to understand source processes of earthquakes, volcanoes, and crustal deformation. Current research focuses on combining numerical modeling of surface deformation of volcanoes, and fault systems on Earth. Current or past science investigator for ERS, ENVISAT, TerraSAR-X, TanDEM-X, COSMO-SkyMed, UAVSAR, and ALOS-2 SAR missions (ESA, DLR, ASI, NASA, JAXA respectively).
