Projects

Things I have built

A selection of full-stack, applied AI, and community projects — favouring practical reliability over polish.

Project Timeline

Where I’ve spent my time, grouped by intent — foundational research, applied products, and communityinitiatives. Bars span each project’s active period; red means still in progress, gray means wrapped.

		20222023202420252026
Research Building knowledge and methods	Human-AI Collaboration in ATC — Contrail Avoidance with Eye Tracking Studying air traffic controller attention management with eye tracking during radar monitoring and coordination with pilots.
	Calibrated Intervention in Human–AI Collaborative Forecasting: How Modification Intensity and Direction Interact to Determine Performance An eye-tracking study of when human corrections improve an AI forecast—and when confident intervention makes it worse.
	CAS 2026 Paper Network From a flat conference programme to an explorable map of related research.
	Interdisciplinary Fusion Project Cross-disciplinary collaboration platform with seminars, mixers, and co-creation workshops at UTokyo.
	Urban Flood Risk Simulation A 5 m city-scale hydrodynamic model evaluated against observed flood reports and independent susceptibility evidence.
Applied / Product Turning research into real-world value	LLM Agent–Embedded Cruise Procurement Platform A full-stack cruise procurement platform that embeds an LLM agent inside an approval-gated workflow spanning document intake, RFQ generation, supplier coordination, and execution.
	RealityAI Floor-plan-aware multimodal property discovery.
	IP Collaboration Candidate Screening A decision-support prototype that narrows a large pool of character IPs to a per-audience shortlist — separating "generally popular" from "a fit for this segment".
	Loomi — AI Creative Canvas A tree-based creative software concept for material-guided, iterative exploration.
Community / Learning Growing together, sharing knowledge	Yujian Reading Circle A purpose-driven, role-agnostic reading community in Tokyo, built around shared interests and in-person conversation.
