About Me

Yu Su

I'm a Distinguished Assistant Professor of Engineering at the Department of Computer Science and Engineering, The Ohio State University, where I co-direct the OSU NLP group, co-lead the Foundational AI team in the ICICLE AI Institute and lead the Machine Learning Foundations team in the Imageomics Institute. I got my PhD from University of California, Santa Barbara and my bachelor's degree from Tsinghua University, both in Computer Science. I also spent some fun time as a researcher at Microsoft Semantic Machines. I'm a 2025 Sloan Research Fellow and received several best/outstanding paper awards from CVPR and ACL.

I'm broadly interested in artificial intelligence, with a primary interest in the role of language as a vehicle for reasoning and communication. These days, I spend much of my time thinking about language agents [blog, tutorial], an emerging class of AI agents characterized by their language understanding and production capabilities.

I'm fascinated by biological intelligence and the power of natural selection, so one may find many references or direct inspirations from biological intelligence in my work. Meanwhile, biological systems also have their constraints and limitations, and I hope to develop advanced artificial intelligence to augment human intelligence. Some facets and applications of intelligence I'm currently interested in:
