Zinan Tang (εζ’ζ₯ in Chinese) is a senior undergraduate student majoring in Computer Science (CS) at the School of Computer Science (Pilot Software Engineering School, SCS), Beijing University of Posts and Telecommunication (BUPT), expecting his B.S. degree in 2026. He has been admitted to the Department of Automation (DA) at Tsinghua University (THU), where he will pursue his masterβs degree in Big Data under the supervision of Dr. Biqing Huang. He currently is an intern of Ant Group.
His research interests are on Data-centric LLMs (e.g., AI4data, data4AI, SFT, post-training, pre-training, reasoning).
