I am now a joint Ph.D. candidate in the School of Electronic Information and Electrical Engineering at Shanghai Jiao Tong University, advised by Rui Zhao. I am also fortunate to be co-advised by Rui Su and Lei Bai at the Shanghai Artificial Intelligence Laboratory.

I received my B.S. degree in Geophysics from the School of Earth and Space Sciences at the University of Science and Technology of China, where I was advised by Prof. Junlun Li.

My research interests lie in developing AI-driven methods for geophysical data analysis, with a particular focus on seismic data processing, remote sensing interpretation, and geophysical inversion techniques, including Full Waveform Inversion and Surface Wave Inversion.
