My research interests include space geodesy and satellite remote sensing. 1. Strain and seismic moment accumulation process: utilizing geodetic methods to estimate fault slip rate, cumulative strain and seismic moment rate, fault and non-fault strain analysis, and related seismic and geological hazards. 2. Surface deformation observation and simulation: large-scale and mesoscale earthquake and interseismic deformation related to fault activities, as well as surface deformation and modeling related to magmatic activity, underground resource extraction, ice movement, hydrologic activity. 3. InSAR data processing: GMTSAR open-source software development (https://github.com/gmtsar), InSAR processing method, time series analysis, etc.
