She has testified on these topics on behalf of both plaintiffs and defendants, from governmental agencies (including the Federal Energy Regulatory Commission and the Department of Justice) to private institutions. Her testimony has also included price artificiality and damages, causation, class certification, bid-rigging, price-fixing and market allocation, market manipulation, fraud, valuation, market definition, mergers and acquisitions, monopolization, and benchmarks reform.

Dr. Abrantes-Metz’s work spans a wide range of industries, including pharmaceuticals, oil and natural gas, transportation, catering, technology and innovation, payments systems and electronic transactions, foreclosures and evictions, trading and pricing algorithms, high-frequency trading and spoofing, precious metals and other commodities, and financial instruments spanning multiple markets.
