My research sits at the intersection of space geodesy and seismotectonics. I use Sentinel-1 and ALOS-2 SAR imagery to build InSAR deformation maps of active faults across Asia, and combine these with GNSS time series to understand how faults slip before, during, and after earthquakes. Current focus areas include earthquake sequences in Afghanistan and the rheological structure of the Himalayan lower crust.
Constructing surface deformation fields from SAR interferograms and inverting them for fault slip distributions — from coseismic rupture to slow aseismic creep.
Analyzing time-series InSAR and GNSS data to separate afterslip, viscoelastic relaxation, and poroelastic rebound following large earthquakes.
Applying rate-and-state friction theory and Coulomb stress analysis to understand fault interaction, earthquake triggering, and lower-crustal rheology.
Field mapping and remote sensing of major fault systems — Philippine Fault, Hindu Kush, Himalayan front — to characterize geometry, segmentation, and seismic hazard.
