$ whoami

Zezhong (aka Zeddy) is a Ph.D. candidate (successive master-doctor program since 2022) in the Data Darkness Lab (DDL) at the School of Artificial Intelligence and Data Science, University of Science and Technology of China (USTC), supervised by Prof. Xike Xie. He was a visiting student at the Department of Computer Science, Hong Kong Baptist University, from 2024 to 2025, working with Prof. Jianliang Xu. He received his B.Eng. (Hons) degree in Computer Science and Technology from Ocean University of China in 2022. He has published several research papers in prestigious conferences and journals such as SIGMOD, SIGKDD, NeurIPS, ACL, and TC. His general research interests mainly focus on the data management, machine learning, and computer systems for big data and large models, particularly big graph data and large language models.
