About
As a space and planetary scientist, I specialize in exploring large datasets and using novel methods to explore planetary interiors. I have developed and applied innovative tools to scan planetary interiors, such as crustal and mantle structures. More information can be found on my personal website.

Research interests
I am currently working on four projects in collaboration with researchers from around the world, including the Australian Space Agency, University of Cambridge, California Institute of Technology, Woods Hole Oceanographic Institution, University of Maine, Nanyang Technological University, and University of Tasmania.
The “Lunar seismology: new missions”; subcontract with Fleet Space Technologies “Moon to Mars: Demonstrator program” funded by the Australian Space Agency (https://fleetspace.com/news/fleet-space-awarded-a4m-demonstrator-program-contract-to-harness-seismic-data-at-moons-south-pole)
“TReaty MOnitoring Research (TREMOR) Consortium: Improving capabilities to detect, locate, discriminate and characterize the depths, yields and emplacement conditions of nuclear explosion” ; US Air Force Research Lab (DoD/AFRL)
“Post-Certification Activities of PS02 and IS07, Warramunga, Australia, funded by the United Nations Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization
“Probing the Australian-Pacific plate boundary: Macquarie Ridge in 3-D”; Australian Research Council Discovery Proposal DP200101854
Details of my research interests are list below:
I simulate coda-correlation wavefield and calculate the sensitivity kernels of the features in the coda-correlation wavefield.
I apply ambient noise full-waveform inversion to image the 3-D S-wave velocity of the crust and uppermost mantle beneath the Macquarie Ridge Complex using OBS data.
I study the the source mechanisms for small earthquakes along the Macquarie Ridge Complex based on 3D wavespeed model.
I have been working on building high-resolution 3-D seismic velocity models for the lithosphere of the Sichuan-Yunnan region (China) using adjoint tomography method since 2020.
Developing 3-D velocity models for the uppermost mantle beneath the Australian continent and lithosphere of the Sichuan-Yunnan region based on the ray-based method.
Numerical simulation of the high-frequency ground motion caused by earthquakes in the Sichuan-Yunnan region and Australian continent.
Imaging the crustal Lg-wave attenuation of the Australian continent and Sichuan-Yunnan region.
Exploring the seismic characteristics of some special earthquakes such as the earthquakes caused by the 15 February 2013 bolide explosion in Chelyabinsk, Russia, and the nuclear explosion in North Korea.
