Research

My research mainly focuses on the seismic structure of the Earth. Currently, one of my projects with Zhongwen Zhan is to seek for the seismic evidence of “Metastable Olivine Wedge (MOW)” which has been hypothesized for decades as a physical mechanism of the deep-focus earthquakes. To untangle the possible MOW signatures from shallow complexities, we use an inter-source interferometry to turn deep earthquakes into virtual receivers by analyzing scattered waves. The existence and geometry of MOW can provide new clues on the deep earthquake physics as well as slab dynamics and mineral properties. We are also exploring the potentials of the coda interferometry method at teleseismic distances. Moreover, under the supervision of Nadia Lapusta, I am involved in an investigation to understand the nature of low-frequency earthquakes on a rate-and-state fault.
