SHORT BIO
Yubo Ma is a third-year Ph.D. candidate in School of Computer Science and Engineering at Nanyang Technological University (NTU). He is co-advised by Prof. Aixin Sun and Prof. Yixin Cao. He received his B.Eng. degree in Electronic Engineering from Tsinghua University in 2020. His research interests lie in event-centric information extraction (including event detection and event argument extraction) and tool-augmented large language models. Currently, he is also a research intern at Microsoft Research (MSR) & Azure AI.
