Selected Work
The Year Measles Came Back
Sixty years of measles data, zoomed from national elimination down to the counties and towns where exemptions cluster — a scrollytold map essay in D3.

Every ontology concept as one yes/no question — 643,520 calibrated answers over 20 PubMed abstracts, DOID and HPO, in minutes for pocket change.

A split-flap (Solari) board you program from the browser — slides of text, countdowns, clocks, and color blocks, with loop, sound, shareable view/edit links, and kiosk mode.

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.
Family History Interface
A structured interface for capturing family medical history.
MTA Icon Menu
A subway-line icon menu built entirely in Altair — data-viz as UI, no HTML/CSS — with a wait-assessment analysis of MTA ridership data.
