Software
Open-source tools and R packages for quantitative social science built to make experimental design, data visualization, and archival data more accessible.
Interactive Dashboards
European Protest & Coercion Dashboard
Browse, visualize, and model Ron Francisco's European Protest & Coercion Data — the most comprehensive daily-resolution record of political contention and state repression in modern Europe. Four tabs: summary statistics, annual trends, a searchable event table, and interactive regression estimation.

R Packages
All packages are available on GitHub. CRAN packages include live download counts.
plotrr
CRAN
Active
Functions for visual exploratory data analysis with nested and hierarchical data. Coauthored with Michael J. Nelson.
colorr
CRAN
Active
Color palettes for EPL, MLB, NBA, NHL, and NFL teams.
nomine
CRAN
Active
Classifies names by probable race/ethnicity and gender using the NamePrism and NamSor APIs. Useful for large-scale audit studies and correspondence experiments where respondent identity needs to be inferred from name data.
repllm
GitHub
Active
A research methodology toolkit for social scientists using LLMs to annotate and classify text. Built on top of ellmer, it adds the methodological layer needed for peer-reviewed research: structured coding runs, reliability assessment (Cohen's κ, Krippendorff's α), sensitivity analysis across prompts/models/temperatures, gold-standard validation, prompt pre-registration, and automated reporting.
validatednamesr
GitHub
Active
A database of 600 names with 44,000+ evaluations across race, income, education, and citizenship — designed for experimental studies on race and ethnicity. Coauthored with Jae Yeon Kim, S. Michael Gaddis, John B. Holbein, Connor Guage, and William W. Marx.

Teaching Software
Kiln — AI-resilient active learning
A real-time active learning platform for university classrooms. Students join with a 6-character code — no accounts, no downloads — and participate in timed, peer-dependent activities that resist AI shortcuts by design. Activity types include Peer Critique, Socratic Chain, Peer Clarification, Evidence Analysis, and AI-powered Scenario exercises (solo and multi-persona).
Civic Town
A live cooperative simulation of Bonotti and Nwokora’s civic model of political finance. Students join with a class code and allocate civic credits across party vouchers and civic institutions, then observe the effects on democratic health indicators — voice, accountability, collegiality, turnout, and funding concentration. Designed to make abstract readings tangible in real time.
The Quota Lab
An interactive classroom tool for exploring electoral gender quotas and representation theory. Students design parliamentary reforms, shape a legislature, and discover what representation really means — drawing on Mansbridge (1999) and Celis & Childs (2020). Includes a parliament simulation game and a representation quiz.
Using one of these tools in your research? I'd love to hear about it — bug reports, feature requests, and coauthorship inquiries welcome.
