What exam scores can and cannot prove about unauthorized AI assistance: Evidence from a highly public classroom episode
Chad M. Topaz, Utsav Bahl
The paper analyzes a public dataset of midterm and final exam scores to show that statistical evidence alone cannot confirm whether students used unauthorized generative AI, highli…
Institutional Harm through Threshold Cascades
Piper Harris, Chad M. Topaz
Can a population of people not individually inclined to harm others nonetheless produce harmful collective outcomes, purely because of the institutional structure they inhabit? Soc…
How Withheld Punishment Enables Authoritarian Persistence: An Evolutionary Dynamics Approach
Chad M. Topaz
Democratic backsliding is often framed as a contest between pro-democratic defenders and anti-institutional norm-breakers. That framing can miss a third behavior, a public that wit…
Topological summaries of fingerprint ridge patterns carry identity information
Chad M. Topaz, Niny Arcila-Maya, Elizabeth Munch +2
Fingerprints are the most widely deployed biometric. Verifying whether two impressions come from the same finger typically relies on minutiae, small landmarks such as skin ridge en…

Oluwatosin Babasola, Olayemi Adeyemi, Ron Buckmire +6
The field of the mathematical sciences relies on a continuous academic pipeline in which individuals progress from undergraduate study through graduate training and postdoctoral pr…
Reliable Topology for Dynamic Data: Mathematical Foundations and Applications
Chad M. Topaz
Across many scientific domains, practitioners rely on coarse, discretized summaries to track the evolving structure of complex systems under noise, measurement error, and changing…
