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.

Research Building knowledge and methods	Human-AI Collaboration in High-Risk Decision Domains with Eye Tracking Modelling human behaviour in high-risk decision workflows using eye-tracking data — the empirical arm of the PhD, spanning six papers across IJHCI, TOCHI, TE, and INCOSE CAS.
	Human-AI Collaboration in ATC — Contrail Avoidance with Eye Tracking Studying how air traffic controllers process contrail-avoidance guidance on radar displays — and how AI decision-support can surface climate-relevant information without adding to their workload.
	Urban Flood Risk Simulation City-scale hydrodynamic flood model at 5 m resolution — driven by observed rainfall, with no tuned parameters, checked against independently reported flood locations.
	CAS 2026 Paper Network The first LLM-built paper network presented at a conference — see where your research sits, at a glance
	Interdisciplinary Fusion Project Cross-disciplinary collaboration platform with seminars, mixers, and co-creation workshops at UTokyo.
Applied / Product Turning research into real-world value	Cruise Business Digital Transformation End-to-end workflow with OCR, LLM validation, and a React + Python stack.
	RealityAI LLM-powered real estate analysis platform: data, retrieval, and product design.
	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 AI + art hackathon prototype — collect scattered inspirations, let a language model draw out relationships between them, and weave them into artworks.
Community / Learning Growing together, sharing knowledge	Yujian Reading Circle A decentralised reading community in Tokyo — 40+ sessions, 600+ participants across disciplines.
