Introduction: I am an Associate Professor in Geophysics in the Department of Geosciences at the University of Texas at Dallas. I am a structural and computational seismologist. I am interested in developing high-accuracy and high-resolution imaging techniques to investigate the crust and mantle structure of the Earth. I got my B.S. at Sun Yet-sen University in 2005, M.S. at Peking University in 2005, and Ph.D. at Princeton University in 2013. From 2013 to 2015, I was a Jackson School Distinguished Postdoctoral Fellow at the University of Texas at Austin. From August 2015, I joined the University of Texas at Dallas. My studies combine seismology, geology, applied mathematics and high-performance computing to investigate physical properties of Earth’s materials, including wavespeed, attenuation, anisotropy and reflectivity. These results play important roles in locating hydrocarbons in the subsurface, as well as understanding the thermal and compositional evolution of the Earth’s interior. During my stay at ERI, we would like to explore the possibility of applying full waveform inversion to data collected by the Pacific Array BBOBS, and investigate the possibility of building 3-D radial/azimuthal anisotropy and shear attenuation models for the Pacific lithosphere and asthenosphere system.
