AI Expert Witness & Economic Consulting

I provide expert analysis and testimony in complex litigation involving artificial intelligence, digital platforms, and technology-driven economic harm. My work focuses on matters where legal outcomes depend on a clear, rigorous understanding of algorithms, data, market structure, and economic impact. I am frequently retained in disputes involving AI systems, platform conduct, API access, and alleged anticompetitive or exclusionary behavior, with an emphasis on methodological rigor, transparency, and clarity under adversarial scrutiny.

Engagement Types

Expert Reports

Written expert reports and declarations with supporting exhibits, designed for admissibility and clarity under scrutiny.

Depositions & Testimony

Deposition preparation and live testimony, including cross-examination support and rebuttal analysis.

Consulting Support

Litigation Domains

AI & Algorithmic Systems

Expert evaluation of model behavior, performance claims, algorithmic decision-making, and causal impact in legal settings, with explanations built for non-technical audiences.
