Epidemiology & Public Health
Model disease transmission dynamics, identify causal risk factors, and discover governing equations of epidemic spread from surveillance data.
One of 34 industries across 8 sectors served by CDE — the Causal Dynamics Engine for Science and Engineering.
The Challenge
Why Epidemiology & Public Health teams still struggle to explain what is happening
Epidemiological data (case counts, contact tracing records, environmental surveillance, genomic sequencing, mobility data) encodes the transmission dynamics of infectious disease and the causal determinants of population health. Public health decisions depend on accurate characterization of disease spread, risk factor identification, and intervention effectiveness. But epidemiological data is observational, confounded by socioeconomic factors, reporting biases, and spatial-temporal heterogeneity. The stakes of analytical error are measured in lives and resource misallocation, making rigorous causal inference and reproducibility essential.
Pre-specified compartmental frameworks (SIR, SEIR, and extensions) impose structural assumptions about transmission dynamics before examining the data. When true dynamics involve heterogeneous mixing, superspreading events, or behavioral feedback loops, these rigid families may misrepresent epidemic trajectories. Causal risk factor analysis depends on regression methods requiring explicit confounding specifications, creating a circular dependency where the analytical framework presupposes the causal knowledge it aims to discover. This is particularly acute during novel outbreaks where prior structural knowledge is unavailable.
The CDE Approach
How CDE closes the explanation gap in epidemiology & public health
CDE discovers governing equations of epidemic spread directly from surveillance data, identifying transmission dynamics, reproduction rates, and intervention effectiveness without pre-specified compartmental models. This captures heterogeneous mixing patterns, time-varying transmission dynamics, and behavioral feedback effects that standard frameworks cannot represent. For chronic disease epidemiology, CDE identifies causal risk factor structures from observational data, separating genuine causal determinants from confounded associations to produce intervention-actionable evidence.
Every epidemiological claim is typed, reproducible, and auditable, meeting evidence standards for policy-informing science. The Truth Dial lets public health teams set confidence thresholds appropriate for different decision contexts, from early outbreak assessment to definitive intervention evaluation. Causal mode separates true risk factors from confounded associations, and negative controls ensure discovered dynamics withstand stability analysis and out-of-distribution testing.
Discovery Engine
How CDE applies here
Causal mode produces causal graphs mapping transmission pathways, risk factor structures, and intervention mechanisms. Symbolic mode discovers closed-form transmission equations and reproduction dynamics that epidemiologists can communicate to policymakers. The Evidence Ledger and deterministic replay provide the reproducibility infrastructure that policy-informing epidemiological evidence demands across outbreak response and long-term public health planning.
Causal Graphs
Discovers directed causal structure from observational data — identifiable causal graphs, regime classifications, and intervention predictions.
Governing Equations
Extracts compact governing laws grounded in the causal structure — interpretable equations your team can read, verify, and compare against known theory.
Intervention Design
Proposes targeted experiments to resolve ambiguous causal edges — maximizing information gain where the causal structure is still uncertain.
Causal Validation
Negative controls, falsification tests, and identifiability analysis applied to every causal claim before promotion to the evidence ledger.
Typed Scientific Claims
What CDE discovers
Every discovery CDE produces is a typed scientific claim — not a black-box prediction, but a governed, reproducible, auditable piece of scientific knowledge with full provenance.
- Transmission dynamics governing equations
- Causal risk factor identification
- Intervention effectiveness models
- Variant fitness landscape laws
- Spatial spread dynamics
Governed Discovery
Make the finding reviewable
Every discovery CDE produces carries the review context around it: a Truth Dial setting, an evidence entry with replay context, and control results including bootstrap stability, out-of-distribution testing, and feature-shuffle validation.
For epidemiology & public health, that means teams can compare runs, justify decisions, and decide whether a finding is ready for internal use, external review, or regulated submission.
