Research Interests

My research interest is to use geodetic techniques (e.g., InSAR, GPS and leveling) to study the geophysical processes that cause deformation of the crust, e.g., earthquake cycle, earth fissuring, urban subsidence, and landslides. The details include: (1) Monitoring and modeling crustal deformation (earthquake cycle); (2) Multi-spatial InSAR time-series analysis (Persistent Scatterer Interferometry (PSI) and Small BAseline Subset Differential SAR Interferometry (SBAS)); (3) Deriving ionospheric perturbations from InSAR and GPS.
