Jung Hoon Son, M.D.
Physician-engineer and visual storyteller — informatics, data visualizations, and insights in healthcare and life sciences. I write about the gap between what models can do and what they actually do.
Selected Work
Working with Data in the Age of GenAI
XPC Hackathon winner. A step-through deck on how analytics work changed — imperative → declarative → English — culminating in a prompt typed into a zsh terminal and a styled chart coming out.
Family History Interface
A structured interface for capturing family medical history.
LOINC Lookup
A Gemini–Google LOINC validator: type a lab test name, get validated LOINC codes back — with cached terms and a hallucination-rate meter.
Geomark
A geography quiz game built for my kid — pick countries and watch them fill the map with their flags; hover to learn size, neighbors, and more. Co-authored with Mark Son.
willitrun
Paste a Hugging Face model, find out if the machine you're holding can run it — real parameter counts, KV-cache math, and PASS/TIGHT/FAIL badges in a terminal UI, with a live trending dashboard fit-checked against your RAM.
Marklee
Annotations that travel with the document — a portable, format-agnostic annotation format for PDF, Markdown, and DOCX. Local-first sidecar JSON, edit-tolerant text anchors, MarkRank centrality over your reading.
