Katsuya Ogata

I am a student at Osaka University majoring in information science, advised by Prof. Yuta Nakashima.

My research centers on Vision and Language: long video editing driven by messages, visual concept reasoning, and the internal representations of multimodal models.

I also enjoy exchanging ideas with researchers abroad, e.g. through the ASPIRE project and ICLR 2026.
