Hi there👋! I’m Kuangshi Ai, a second-year Ph.D. student in Computer Science and Engineering at the University of Notre Dame, where I work with Prof. Chaoli Wang in the ND-VIS Lab. I received my bachelor’s degree in Artificial Intelligence from Fudan University in July 2024. During undergrad, I spent a semester as an exchange student at the University of Sydney and conducted summer research with Prof. Toby Li at Notre Dame.

My research interests lie at the intersection of scientific visualization, human-computer interaction, and natural language processing. I develop multimodal, agentic LLM systems that make complex visualization and 3D/4D data interaction more intuitive, expressive, and accessible to broader audiences. A key part of my current work involves evaluating LLM agents for SciVis by building benchmark datasets and frameworks that assess their capabilities, limitations, and interaction behaviors.

More broadly, I’m excited about HCI + VIS + AI, interfaces for generative and multimodal models, 3D interaction and authoring, agentic workflows, and the future of intelligent, mixed-initiative visualization systems.

If you’re interested in my work or would like to collaborate, feel free to reach out at kai[at]nd[dot]edu.
