I am currently a Huashan Elite Associate Professor at Xidian University, starting from September 2026, joining the group of Dahua Gao. I received my Ph.D. degree in Computer Science and Technology from Xi'an Jiaotong University (XJTU) in June 2026, advised by Jun Liu and Lingling Zhang. My research interests mainly include Understanding, Reasoning, and Applications of Large Language Models and Agent Systems. From October 2024 to October 2025, I was a visiting student at the Centre for Frontier AI Research (CFAR), A*STAR, Singapore, mentored by Basura Fernando and Mike Shou from the National University of Singapore. I received my B.Eng. degree in Computer Science and Technology from Xi'an Jiaotong University in 2021. During my undergraduate studies, I was part of the "Huawei Cloud" AI Elite Class program and pursued a minor degree in Automation. If you are interested in my research, please feel free to contact me via email: zhibei1204@gmail.com or 1393869716@qq.com.
