My research aims to understand the dynamics and societal impacts of deformation and seismicity in the Earth’s crust due to natural processes or human activities, including microseismicity, fault creep, major earthquakes, ground uplift and subsidence, and their interactions in geothermal fields, crustal faults, and subduction zones. I combine analyses of geodetic datasets, e.g., Global Positioning System (GPS) and Interferometric Synthetic Aperture Radar (InSAR), with seismological observations and laboratory-based computational modeling to study these geophysical processes over multiple time scales (from seconds to centuries) and their behavior under transient or steady environmental forcing. Through such interdisciplinary efforts, I hope to further our understanding and assessment of natural hazards such as earthquakes and tsunamis, and improve the monitoring and mitigation of induced hazards during geo-energy explorations such as hydraulic fracturing and geothermal energy production.
