I investigate organized crime, cross-border security, and governance to produce nuanced analysis and practical recommendations that public institutions can use responsibly.
Original research · Wilson Center
Arms Trafficking Across the U.S.–Mexico Border
I analyzed six years of government records and open sources to examine how firearms moved from legal markets in the United States into Mexico.
The Wilson Center published the work, and Mexico News Daily republished it. It was later cited in a U.S. Supreme Court amicus brief and academic publications. Project staff also confirmed that it was presented in briefings with State, Commerce, and DHS officials.
