I am interested in deformation of the Earth's crust due to earthquake faults, magmatic sources, and other manifestations of active tectonics. I use space geodetic observations (primarily from Interferometric Synthetic Aperture Radar and Global Navigation Satellite Systems), numerical models, and laboratory experiments to understand how the Earth responds to various kinds of natural and anthropogenic forcing.

• The 2023 M7.8-7.7 Turkey earthquake doublet
• The 2019 M7.1 Ridgecrest earthquake
• The 2010 M7.2 El Mayor-Cucapah (Mexico) earthquake
• Interseismic strain accumulation on the Southern San Andreas fault
• The 2003 Bam (Iran) earthquake
• The 1992 Landers earthquake
• Co-seismic strain localization due to compliant fault zones
• Rupture characteristics of M7.1 Hector Mine earthquake from inversion of InSAR and GPS data
• Crustal uplift due to inflation of the Socorro Magma Body, New Mexico
• Magmatic unrest in the Long Valley caldera, eastern California
• Study of deformation in the Coso geothermal area, central eastern California
