About Me
I am an associate researcher with the College of Geophysics at Chengdu University of Technology (CDUT). Before joining CDUT, I completed a two-year postdoctoral research program at Peking University (PKU) in 2022. I obtained my PhD in Solid Earth Physics in 2020 from Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS), and BE in Applied Geophysics in 2014 from Jilin University (JLU). I am currently a visiting scientist at University of Padua (UNIPD), working with Prof. Manuele Faccenda on seismic anisotropy tomography methods.
My research interests include:
- Observational seismology
- Signal Processing in Seismology
- Imaging of seismic Anisotropy
- Structure, evolution, and deformation of continental lithosphere

Research
Imaging of seismic anisotropy
I am deeply interested in advancing seismic anisotropy tomography methods, with a particular focus on shear wave splitting tomography. My work involves applying full-wave anisotropy tomography techniques using shear wave splitting intensity data to explore the anisotropic characteristics of the Earth's crust and mantle.
► Full-wave anisotropy tomography
Signal Processing in Geosciences
I develop signal processing techniques to improve data quality in geosciences, including denoising Nanoscale secondary ion mass spectrometry (NanoSIMS) data and seismic data.
► Seismic Data Denoising
Attenuating random noise is crucial in seismic data processing. We have developed two methods, PID and MDF, to effectively reduce random noise in seismic data. Numerical examples demonstrate that both methods outperform conventional denoising techniques, delivering superior results.
► NanoSIMS image enhancement
We applied the weighted nuclear norm minimization (WNNM) method to reduce the random noise in the NanoSIMS image. The low-rank property of the image is fully considered to suppress random noise while retaining reliable details of weak signals.
