I am currently a Master’s student at the Department of Software Engineering, Xi’an Jiaotong University (XJTU), advised by Prof. Jihua Zhu. I graduated from School of Computer Science and Technology, Taiyuan University of Technology with a bachelor’s degree. I am collaborating closely with Ning Yang at the Institute of Automation, Chinese Academy of Sciences (CASIA).

🚀I am now working on LLM Reasoning and Chain-of-Thought (CoT). Currently, I am actively seeking Ph.D. opportunities for the Fall 2027 intake. I am particularly interested in advancing LLM Reasoning and Multimodal Learning. If you are looking for a self-motivated student with a strong background in 3D-Vision and LLM, or if you are interested in academic collaboration, I would be honored to discuss further via email at zhangdongxu@stu.xjtu.edu.cn.

🔥 News

Currently, I am a Visiting Student at the Shanghai Artificial Intelligence Laboratory (Shanghai AI Lab), where I am privileged to be advised by Cheng Tan. My research primarily focuses on AI for Science and LLM Reasoning.

[Jan. 2026] 🔥 Excited to share our new preprint “Chain-of-Thought Compression Should Not Be Blind: V-Skip for Efficient Multimodal Reasoning via Dual-Path Anchoring” on arXiv! We propose V-Skip to address “Visual Amnesia” in MLLM reasoning compression. Check out the paper and project page!

[Jan. 2026] 🎉 Excited to share that our paper “IGASA: Integrated Geometry-Aware and Skip-Attention Modules for Enhanced Point Cloud Registration” has been accepted by IEEE TCSVT!

[Jan. 2026] 🎉 Excited to share that our paper “CMHANet: A Cross-Modal Hybrid Attention Network for Point Cloud Registration” has been accepted by Neurocomputing!

[Jan. 2026] 🎉 Excited to share that our paper “DEEP LOCAL FIELD CONSISTENCY FOR NON-RIGID POINT CLOUD REGISTRATION” has been accepted by ICASSP!
