Biography

Welcome! I am an incoming PhD student at the School of Computer Science and Technology, Harbin Institute of Technology, Shenzhen (HITSZ), advised by Professor Jianlong Wu and Professor Liang Han.

Prior to my PhD, I received my Master’s degree in Artificial Intelligence at MIMA Lab, School of Software, Shandong University in 2025, advised by Associate Professor Xin Luo, co-advised by Professor Xin-Shun Xu. During my master studies, I also worked closely with Associate Professor Zhen-Duo Chen and Professor Peng-Fei Zhang. Before that, I received my Bachelor’s degree in School of Information Science and Engineering, University of Jinan, China, in June 2022, supervised by Professor Xiuyang Zhao. I deeply appreciate the dedicated guidance and support.

My current research interests focus on Long Video Understanding and World Models. During my master’s, my work primarily revolved around online hashing and image/cross-modal retrieval, which laid the groundwork for my current shift toward these areas.

If you are interested in my topics, please do not hesitate to reach out.
