Research Interests

Interferometric synthetic aperture radar (InSAR), terrain modeling and monitoring/inversion of ground deformation related to landslide, earthquake, alpine glacier and volcano.

My research has concentrated on development of the advanced radar interferometry techniques such as persistent-distributed scatterer radar interferometry, ground-based SAR system and the relevant software package. As the principal investigators, I have conducted investigations on the relevant algorithms and methods with support of over 20 research projects granted by the national-, provincial- and ministerial-level research funds (e.g., the National Natural Science Foundation and the National Key R&D Program). These new processing approaches developed by the investigations have been applied to reconstruct 3D models of terrain, monitor and inverse subsidence caused by groundwater withdrawal in urban areas and along linear structures such as high-speed railway, as well as ground deformations related to landslide, earthquake, alpine glacier and volcano.
