Litigation counsel
Independent analysis and sworn opinions in AI and machine-learning validation, epidemiology and biosurveillance, food-system and supply-chain risk, and critical-infrastructure resilience. Reports written to survive cross-examination.
Expert witness →Corporate and government
Threat, vulnerability, and risk assessment. Biosurveillance architecture. Open-source network and influence analysis. Security technology evaluated against liberty, security, and cost.
Consulting and advisory →Technology leaders
Detection systems, AI decision support, and internal knowledge systems delivered on fixed fee milestones with objective acceptance criteria.
Technology builds →Event and media bookers
Keynotes, executive briefings, and courses on biosecurity, risk, AI, and national security.
Speaking and training →Systems I have built
GRITS
Global Rapid Identification of Threats System: production natural-language processing that detects outbreaks in open text where no laboratory exists. Built as principal investigator on a $5.8M Defense Threat Reduction Agency program, then independently evaluated and verified in the peer-reviewed literature.
Interdisciplinary Perspectives on Infectious Diseases, 2016 →CRISTAL
Criticality Spatial Analysis: DHS-funded supply-chain mapping and spatial vulnerability assessment developed at the Food Protection and Defense Institute after his evaluation of FASCAT, the sector’s prior tool, exposed its problems. Patent application filed; protected as a trade secret.
Risk Analysis, 2015 (the FASCAT evaluation) →FLIRT
Flight-network model that predicted the United States arrival states for Zika before the cases appeared, validated against the epidemic as it unfolded.
PLoS Currents Outbreaks, 2016 →How I work
Evidence first.
Sources cited, methods stated, every claim traceable to a document.
Known, assessed, unknown.
A hard line between the three, stated every time.
Bottom line first.
Written for the person who has to decide, then the analysis that supports it.

About
I spent my career inside the institutions that are supposed to protect you: the Army, national laboratories, the biodefense enterprise, and the pandemic-prediction organization at the center of the COVID-19 origins question. What I learned is that when protecting the public conflicts with protecting the institution, the institution usually wins. My work is built to break that pattern.
