Academic Profile

At the University of Science and Technology of China (USTC), I obtained my geophysical Bachelor (2004) and Ph.D degrees (2009) in the department of Earth and Space Sciences. During my Ph.D study, I visited SeismoLab of Caltech from 2008 to 2009, working with Prof. Don Helmberger on recognizing wiggles on the seismogram. This was followed by my postdoctoral time at SeismoLab in 2009 until 2014. My research interests are mainly focused on earthquake source studies both in real time and later in-depth research. Recently, I have also become interested in slab structures and their impact on source studies. Besides working on waveform modeling, I am also working with Prof Avouac and other colleagues at Caltech and JPL (e.g. Eric Fielding) to include results from optical and SAR imaging of ground deformation. Collaborations with USGS researchers Robert Graves and Kenneth Hudnut are also part of my research related to seismic hazards. My research experiences cover both natural and man-made earthquakes. My approach for resolving the kinematic nature of earthquakes involves the combination of geodesy, geology and seismology to better constrain the spatial-temporal evolution of seismic rupture properties. Besides reconciling various datasets, I have developed techniques that allow waveform inversions to be extended to the higher frequency (>1Hz) range of relevance for damage assessment. Path calibrations also allow us to report earthquake source parameters more accurately in real time, and warnings can be issued based on these information.
