General

The primary goal of my research is directed toward understanding the structure, dynamics, and evolution of the Earth's interior. In recent years, I use seismic waves to probe the internal structure and property of the upper mantle. Using waveform modeling, tomography, receiver function, and shear wave splitting, I placed high-resolution seismological constraints on basin-range coupling, crust-mantle interaction, lithospheric structure, upper mantle structure and deformation, and evolution of continent. In the recent years, I focus the observation and research on eastern China, a continental margin that underwent complex tectonic events from the Precambrian to Cenozoic. I also have a strong interest in developing new methodologies for simulating seismic wave propagation through the heterogeneous and anisotropic media. The calculation techniques I employed include finite difference, finite element and spectral element methods.
