About

Biography

I am a Ph.D. candidate in Geophysics at the University of Southern California since 2021. I received my B.Sc. in Geophysics from Peking University in 2020. Before joining USC, I was a Research Assistant at the Institute of Geophysics, China Earthquake Administration, from 2020 to 2021. In June 2025, I will join the Seismological Laboratory at Caltech as a Postdoctoral Scholar Research Associate in Geophysics.

Research Interests

As an observational seismologist, my research interests span from the shallowest crust to the deepest inner core. My current work focuses on investigating earthquake source properties and exploring heterogeneities within the Earth. While I believe that the first principle of seismology is reading seismograms, I also appreciate the philosophy of modelers and experimentalists. By integrating diverse observational datasets with theoretical methods and computational tools, I aim to provide novel insights into the intricate interplay between seismic processes and Earth's complex structure and dynamics. I believe that an exemplary geophysical model should be elegant in its simplicity.
