Data Explorations
Interactive data visualizations and analytics projects. These aren't metrics about me - they're data projects themselves that you can explore.
CityDensity - Population Measurement
Project ID: CITY-2024-003 | Status: ⚪ Completed | Views: Millions
What This Shows
Traditional density metrics (people per km²) are misleading. This visualization shows true urban density by measuring how many people live within walking distance of any point. Paris is denser than Manhattan by this measure.
How I Built This
Built with R and Shiny. Uses GIS data to calculate population within 1km radius of every point in a city. Went viral on urban planning Twitter.
Tech stack: R, Shiny, sf (spatial data), OpenStreetMap
PassBox - Cycling Safety Maps
Project ID: PASS-2018-001 | Status: ⚪ Completed | Impact: Law changed
What This Shows
Heat map showing where cyclists experience unsafe vehicle passing. Based on 60,000 measurements from bike-mounted ultrasonic sensors. Red = dangerous, green = safe.
How I Built This
Arduino ultrasonic sensors mounted on bikes. ML pipeline to filter false positives. Leaflet map with aggregated data. This data helped pass 1-meter passing laws in Victoria.
Tech stack: Arduino, Python (ML), Leaflet, PostgreSQL/PostGIS
COVID Modeling - Scenario Comparison
Project ID: COVID-VIC-2020 | Status: ⚪ Published | Impact: Elimination achieved
What This Shows
Agent-based SEIR model comparing COVID elimination vs suppression strategies. Informed Victoria's decision to pursue elimination. Published in peer-reviewed journal.
