Senior Counsel, Justice

Rosemary “Ruby” Nidiry is a senior counsel in the Brennan Center’s Justice Program, where she manages the program’s Law Enforcement Leaders to Reduce Crime and Incarceration project. This is a national coalition of nearly 200 police chiefs, correctional officials, and federal and state prosecutors committed to promoting laws and practices that more effectively fight crime while reducing unnecessary imprisonment.

Before joining the Brennan Center, Nidiry was the deputy director of Fair and Just Prosecution, a national organization that brings together elected local prosecutors committed to furthering a new vision for prosecution. Previously, she served for a decade and a half as an assistant U.S. attorney in the Southern District of New York. She has also held positions at the Office of Legal Counsel and the National Security Division of the U.S. Department of Justice, and she served as the director of criminal justice for the Laura and John Arnold Foundation.

Nidiry holds a BA from Princeton University and a JD from Columbia University. She began her career as a law clerk for Judge Robert P. Patterson of the U.S. District Court for the Southern District of New York and for Judge Carlos F. Lucero of the U.S. Court of Appeals for the Tenth Circuit in Denver. She serves on the board of directors of the Women’s Prison Association, the nation’s first organization for women impacted by incarceration.
