Kei Katsumata

About

I am a Ph.D. student in Information and Computer Science at Keio University, advised by Prof. Komei Sugiura. My research centers on embodied AI — building agents that perceive, reason, and act in the physical world, spanning autonomous driving and mobile manipulation. I connect vision and language with grounded action, so that systems can follow natural-language instructions and operate reliably in real-world environments.

Alongside research, I work as a full-stack engineer with experience building scalable applications in TypeScript and Go on modern cloud infrastructure, combining research insight with practical software engineering.

Research Interests

• Vision and Language — Multimodal Retrieval, Referring Expression, Instruction Generation
• Computer Vision — 3D/4D Reconstruction
• Embodied AI — Autonomous Driving, Mobile Manipulation
