Personal Interests

Dr. Sarro is principal and director of The Brattle Group, and a leader of its practice in cases involving “big data” and document analytics. He is a financial and empirical economist who is the lead consulting expert to investigative and trial teams in complex investigations and high-stakes litigation. He applies detailed financial models and statistical analyses to quantitative and qualitative data to identify critical evidence used to inform case theory or expert analysis.

Dr. Sarro specializes in cases involving complex questions of financial conduct, incentives, and value, frequently in the context of fraud or breaches of contracts, market regulation, or law. Much of his recent work involves false claims, financial market fraud, structured finance transactions, and shams. His recent cases include several financial crisis-related fraud cases, including the $1.4 billion Standard & Poor’s credit ratings case, the $1.3 billion Bank of America “hustle” case, and the $714 million Bank of New York Mellon FX Standing Instruction case. His current cases involve faulty financial reporting, kickbacks, mortgage finance and securitization, money laundering, and securities violations.

Dr. Sarro has nearly 20 years of experience working with top academics, executives, and litigators in several areas of legal and business practice to clearly convey answers and analytic approaches to business decision-makers, policymakers, regulators, and courts.

Previously, Dr. Sarro was an associate at Putnam Hayes & Bartlett and The Brattle Group. He also was a principal and office director at LECG. He rejoined Brattle from Watermark Economics, an economic and policy consultancy he co-founded.
