Marc Meyer

Adjunct Faculty

Marc Meyer is an adjunct professor in George Mason University's Criminology, Law, and Society Department with more than three decades of leadership, investigative, intelligence, and instructional experience.

He currently serves as the Deputy Inspector General for Investigations (DIG) at the U.S. Securities and Exchange Commission (SEC) Office of Inspector General (OIG). DIG Meyer revamped and now oversees a team of federal law enforcement officers conducting criminal investigations into conduct affecting the integrity of the SEC’s programs and operations, including SEC staff and contractors, and the SEC's oversight of financial markets; public corruption; and major fraud. Having set new investigative priorities for the SEC OIG and for the first time in the history of the organization, embracing the OIG's broad investigative jurisdiction, DIG Meyer's team is now recognized as experts on securities fraud matters, serving on Joint Duty Assignments with the FBI, and leading interagency criminal financial fraud investigations.

His career in public service includes service as a commissioned officer in the U.S. Foreign Service and in the U.S. Army. He has led and overseen global criminal, civil and administrative investigations into major financial fraud, money laundering, securities violations and schemes, human trafficking, drug trafficking, violent crimes and child sexual abuse, theft and product substitution, bribery, internal affairs and other public corruption, false claims act violations, anti-trust and procurement integrity act violations, counterterrorism and counterintelligence, government employee integrity issues and present responsibility determinations. His work resulted in hundreds of millions of dollars in recoveries, restitutions, savings, and fines as well as decades of incarceration for criminal actors, innumerable suspensions and debarments for individuals and entities lacking present responsibility, and new legislation and policies affecting the oversight of myriad United Nations components and other international organizations.

DIG Meyer brings a global perspective and diplomatic approach to his teaching, leadership, and oversight work, having served in some of the highest risk, war-torn corners of the world at the heights of violence and kinetic activities, including Iraq, Yemen, and Ukraine. He has served throughout the federal oversight community, recently leading the OIG for the U.S. Agency for International Development (USAID), serving as a career member of the Senior Executive Service and the USAID OIG Assistant Inspector General for Investigations, and training criminal investigators at the IG Criminal Investigator Academy. He previously served in the Department of Justice OIG as a Special Agent and in the Department of State OIG as both an Assistant Special Agent-in-Charge and Special Agent-in-Charge – both entities with oversight responsibilities for other federal law enforcement agencies and officers with major national security implications. He began his federal law enforcement career domestically and overseas as a Special Agent in the Department of State’s Diplomatic Security Service running criminal investigations, protective operations, and managing security programs around the world.

In addition to his bona fides as a leader in diplomacy, defense, and development, DIG Meyer is a former intelligence officer and licensed attorney in good standing. He practiced law in New York and New Jersey, served as the first federal judicial law clerk for the Honorable Peter G. Sheridan (Senior U.S. District Court Judge, retired) in the District of New Jersey, served in the Port Authority of New York and New Jersey’s litigation department, litigated in private practice on a white-collar investigations and criminal defense team, and externed at the U.S. Attorney’s Office for the District of New Jersey.

He is sought after to teach. He educates and mentors graduate students and Senior Executives alike as an adjunct professor at George Mason University and the Inspector General Criminal Investigator Academy, where he focuses on leadership, professional development, U.S. Constitutional law, search and seizure, and the intersection of privacy rights and law enforcement/intelligence gathering. In 2026, the U.S. Department of Justice solicited Meyer to join them at the International Law Enforcement Academy in Budapest, Hungary to teach a course on procurement fraud, big rigging, and collusion.
