I am a data visualization specialist with more than a decade of experience designing interactive stories, maps, graphics, and reporting systems in close partnership with public health researchers and policy experts.

Medicaid & CHIP Scorecard
Center for Medicaid & CHIP Services
This public transparency website reports important data about the Medicaid and Children's Health Insurance (CHIP) programs. I collaborated with a cross-functional team of designers, developers, and researchers to deliver user experience designs, data visualization concepts, and high-fidelity prototypes depicting a range of interaction patterns across 50+ performance measures.
Health Systems Explorer
Agency for Healthcare Research Quality
This dashboard visualizes networks of health care providers in the United States alongside their excess readmission rates for six clinical metrics. I pitched the initial concepts, charts, and prototypes through an iterative process with researchers and subject matter experts. I also implemented aspects of the design as member of the development team.
Rural Health Dashboard
Mathematica Policy Research
Rural hospitals provide a lifeline for remote communities in the United States. Advised by experts at Mathematica, I designed interactions for a map-based application that visualizes unplanned, preventable hospital service expenditures in these locations. I also contributed to the project as a frontend developer.
Demographic Disparities in Stroke Care
Mallinckrodt Institute of Radiology
Our team observed that substantial variation in access to certified stroke treatment centers disproportionately affects rural, elderly, American Indian, and uninsured groups of people. I created a series of programs for traversing graph networks, crunching demographic data, simulating clinical populations, and reproducing analyses for more than 80,000 census tracts.

St. Louis, Divided
City of St. Louis
Did you know that St. Louis is one of only three independent cities in the United States? As a result, regional politics are expressed in two distinct governments: the City and the County. This brief story visualizes a few of the demographic disparities existing along these lines.
