I am broadly interested in the processes that deform the solid earth, such as earthquakes, volcanoes, earth tides, hydrological loading, etc. One of my current research focuses is on using space geodesy, including GPS and InSAR (Interferometric Synthetic Aperture Radar) to study the crustal deformation during earthquake cycles.
During my PhD study at Scripps Institution of Oceanography, I worked with Prof. Yuri Fialko on crustal deformation due to several recent large earthquakes around the Tibetan Plateau. We studied the postseismic deformation following several large dip-slip earthquakes at the margins of the Tibetan Plateau, including the 2005 Mw 7.6 Kashmir (Pakistan) earthquake, the Mw 7.9 2008 Wenchuan (China) earthquake and the 2015 Mw 7.8 Gorkha (Nepal) earthquake. Postseismic deformation following these events are characterized by an uplift on the hanging wall side of the fault. This pattern is best explained by afterslip on or below the seismic rupture. The observed postseismic transients do not support a hypothesis of a low (<10^18 Pas) viscosity channel beneath Tibet.
I am currently a postdoc researcher at Seismological Laboratory in UC Berkeley, working with Prof. Roland Burgmann on tectonic deformation. We attempt to use SAR data from the ongoing Sentinel-1A/B mission, in combination with available ground-based measurements (e.g. GPS), to map the large-scale as well as detailed surface deformation field inside the Tibetan Plateau.
