As a senior executive, Mary helped lead the agency’s response to unprecedented maritime and supply chain challenges, including global supply chain disruptions that tested the resilience of U.S. trade and transportation systems. She represented the Commission in high-level interagency initiatives advancing national priorities related to transportation, economic competitiveness, and infrastructure investment. Her federal service provides a nuanced understanding of the intersection of regulation, competition policy, enforcement, and global commerce. Prior to her federal service, Mary clerked for the Superior Court of New Jersey, Criminal Division.
