Mathematical models for real systems.

From pattern formation and nonlinear mechanics to scientific institutions, reliability, and experimental design: reproducible computation, explicit assumptions, and honest limits turn models into testable research questions.

When Taking Turns Makes a System Unstable

Equal update counts do not guarantee stable feedback. A delayed two-choice model shows why allowing one extra slot between updates can stabilize a system, and why its smallest fairness relaxation is not its fastest schedule.

When Early Warnings Cannot Tell the Difference

A system that recovers slowly and an environment that persists can leave the same statistical signature. An exactly sampled stochastic experiment shows what passive monitoring can identify, and which extra observations change the question.
