Research

Subduction zone stucture and dynamics

I study upper mantle deformation beneath the Alaska subduction zone using SKS splitting intensity tomography method. The derived 3D anisotropy model characterizes depth-varying mantle fabrics, providing key constraints on slab retreat, mantle flow, and lithosphere-asthenosphere coupling (Lin et al., 2026).

Alaska

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 crust and mantle (Lin & Zhao, 2024; Lin et al., 2026).

Full-wave anisotropy tomography

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 (Lin & Zhang, 2020, 2022).

Seismic Data Denoising

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 (Lin et al., 2020).
