About me: Ziyi Ye（叶子逸）

I am now a final year Ph.D. student in THUIR, Department of Computer Science and Technology in Tsinghua University, Beijing, China. My supervisor is Prof. Yiqun Liu. My major research interests are about Web search, brain machine interface, large language models, and etc.

I served as a reviewer and SPC/PC member for Nature Comm. Bio., ICLR, Neurips, TOIS, SIGIR, WWW, MM, CIKM, TOMM, and KDD. I am the CCIR Student Contact since 2024, please contact me if you have any questions about IR matters.
