With 25 years of experience working with top academics, executives, and litigators, Dr. Sarro has served as a lead consulting expert for investigative and trial teams in complex civil and criminal financial fraud cases and commercial disputes.

Cases he has worked on have involved blockchain and cryptocurrency tracing, faulty financial reporting, misrepresentations and false claims, kickbacks, money laundering, public corruption, securities violations, sanctions violations, and structured transactions.

Dr. Sarro has been a lead consultant on several high-profile cases, including the Galanis, Meli, KIT Digital, and Premium Point investment fraud cases; the Haider and Liberty Reserve anti-money laundering cases; the Buffalo Billions and Calk bribery cases; Ng Lap Seng and Patrick Ho FCPA cases; Panama Papers and S&P credit ratings investigations; and the Countrywide/Bank of America “hustle,” Allied “shadow loans,” and Novartis speaker programs False Claims Act cases.
