Expert witness
Analysis and testimony that survive cross-examination.
I state my methods, show my data, and separate what is known from what is assessed. Opinions are grounded in formal epidemiologic validity theory, the same framework of sensitivity, specificity, bias, confounding, and measurement error that governs whether a machine-learning system, a surveillance system, or a causal claim can be trusted.
Areas of expert opinion
Artificial intelligence and machine learning
Validation, verification, and reliability of machine-learning and NLP systems. Training-data bias, selection bias, and confounding. Sensitivity, specificity, and error-rate analysis. Whether a model was tested against ground truth, whether its documentation is adequate, and whether it is fit for its claimed purpose.
Epidemiology and biosurveillance
Infectious-disease epidemiology, outbreak investigation, forensic and causation analysis, disease modeling and forecasting, surveillance-system design and failure analysis, exposure assessment. DoD and FBI trained forensic epidemiology investigator.
Food-system and supply-chain risk
Food-system criticality and vulnerability assessment, food defense and contamination risk, supply-chain mapping and single-point-of-failure analysis, recall and foodborne-illness causation.
Critical-infrastructure resilience
Cascading-failure and interdependency analysis, spatial and geospatial risk assessment, resilience of tightly coupled systems.
Security engineering and threat assessment
Threat, vulnerability, and risk methods across physical, cyber, and biological threat models. Standard of care and foreseeability.
Research integrity and federal grant compliance
Grant terms, reporting obligations, oversight failures, and institutional conduct, informed by two years as vice president inside a federally funded research organization.
