About.

I am a PhD candidate in Tokyo/Chiba. My research asks a simple question: can a machine tell how stressed you are just by looking? The notebook catches me mid-turn — from reading pulse and skin signals out of video, toward asking whether the big vision-language models can learn to feel any of it.

Before the research there was writing, and before the writing there was a long detour — the essay below tells that part better than a bio can. I write in three languages, think mostly in two, and keep the important things in one place: this notebook.
