Research Summary

My research interest lies in a range of geophysical processes, including but not limited to:  earthquake seismology, fault and earthquake mechanics, hazards migitiation of earthquakes and tsunamis. I am particularly interested in combining observational and theoretical efforts to mitigate hazard and elevate the understanding of the mechanics of earthquakes.  

Observational seismology

A focus of my research is to develop a new method of earthquake imaging: Multi-array local Back-projection (MLBP). It achieves results with higher resolution within shorter time compared to traditional back-projection methods when the existing local arrays are dense enough (For M 8-9 earthquake, station gap ~ 20 km, For M 6-7 earthquake, station gap ~ 10 km). The related research includes:

MLBP application1: tsunami warning system

MLBP application2: the 2019 Ridgecrest earthquakes

When dense local arrays are not available, teleseismic back-projection is a good tool to recover the rupture process of earthquake that we are interested in with high resolution. We  combined multiple phases and arrays to increase the 3D resolution of the subsources. Here are some application:
