<div id="About me"> <A NAME="About me"><h2>About me</h2></A> </div>
<p>I returned to <a href="http://en.xjtu.edu.cn/">Xi'an Jiaotong University</a> in January 2026 and currently serve as a Researcher in the School of Information and Communications Engineering.</p> <p>Previously, I received my Ph.D. from Xi'an Jiaotong University in 2022 and then held postdoctoral positions at the <a href="https://www.ualberta.ca/index.html">University of Alberta</a> and <a href="https://www.purdue.edu/">Purdue University</a>. To date, I have published 36 SCI-indexed papers. I serve as an Associate Editor of <i>Geophysics</i> and the <i>Journal of Geophysical Prospecting</i>, a Young Editorial Board Member of <i>China Petroleum Exploration</i>, <i>Energy Geoscience</i>, and <i>Oil Geophysical Prospecting</i>, and have served as the IMAGE technical area chair at the SEG Annual Meeting (2023, 2024) and as a reviewer (2025, 2026). I am also an editor of <i>Earth Sciences</i> and a guest editor of <i>Frontiers in Earth Science</i>.</p>
<h2>Research Areas</h2>
<p>Our group focuses on the frontier interdisciplinary direction of "AI + Geophysics" and is committed to using the latest AI technologies to solve core scientific problems in deep Earth exploration. Our current research includes:</p>
<ul>
<li>🔥 Generative AI (diffusion models, GANs, and flow models) for innovative applications in scientific data modeling and inversion</li>
<li>🔥 Self-supervised and zero-shot deep learning, together with neural implicit representations, for intelligent signal processing under severe label scarcity</li>
<li>🧮 High-dimensional tensor computing and compressed sensing, leveraging modern mathematical tools for efficient processing of massive geophysical datasets</li>
<li>🌍 Multimodal intelligent sensing for the fusion and interpretation of seismic, DAS fiber-optic, ground-penetrating radar, borehole imaging, and other heterogeneous data</li>
<li>💻 High-performance scientific computing to support large-scale inversion and imaging algorithm design</li>
</ul>
<p>Students with backgrounds in information and communication engineering, electronic science and technology, computer science, mathematics, geophysics, and related fields are welcome to join us.</p>
