What exam scores can and cannot prove about unauthorized AI assistance: Evidence from a highly public classroom episode
Chad M. Topaz, Utsav Bahl
In spring 2026, an economics professor at Brown University gave a take-home midterm and, after unusually high scores, made the final exam proctored. Among the 59 students who compl…
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…
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…
A Discrete-Time Model of the Academic Pipeline in Mathematical Sciences with Constrained Hiring in the United States
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…
A dynamical model of the U.S. mathematics graduate degree pipeline
Chad M. Topaz, Oluwatosin Babasola, Ron Buckmire +5
We present a latent-stock compartmental framework for modeling degree production systems when only completion flows, rather than enrollments, are observed. Applied to U.S.\ mathema…
