Independent Research Platform
Independent research and evaluation to strengthen safety, accountability, and decision-making.
Directed by John DeCarlo, Ph.D.
Our Mission
Policing Research provides empirical analysis, evidence synthesis, and applied evaluation for agencies, policymakers, researchers, attorneys, and foundations. All work is grounded in transparent methods, peer-reviewed scholarship, and real-world operational experience.
Research Areas
Empirical analysis of officer decision-making under threat, including the first randomized controlled trial on contagion shooting (2024).
Assessment of training methodologies and their impact on operational outcomes, including DOJ COPS Office reports on police education.
