picture of Peter Wagner Peter Wagner is an attorney and the Executive Director of the Prison Policy Initiative. He co-founded the Prison Policy Initiative in 2001 in order to spark a national discussion about the negative side effects of mass incarceration. His report, Importing Constituents: Prisoners and Political Clout in New York, launched the national movement to end “prison gerrymandering” more than a decade ago. His research and advocacy caught the attention of the press — including 21 New York Times editorials — and led multiple states and more than 200 local governments to end prison gerrymandering.

Under his leadership, the Prison Policy Initiative has helped propel other parts of the criminal justice reform movement forward by achieving critical victories in regulating the exploitative prison and jail telephone industry and quantifying the counter-productive effects of geography-based punishments.

Through strategic collaborations, he has brought the need for criminal justice and electoral reform to new audiences, including authoring reports exposing the "whole pie" of mass incarceration, helping Hank Green explain the failed mass incarceration experiment in a VlogBrothers video, working with Josh Begley to put each state’s overuse of incarceration into the international context, and putting the problem of prison gerrymandering onto theatre screens nationwide.

In recognition of the victories he led on this and other issues, he is the recipient of the National Association of Criminal Defense Lawyers’ Champion of State Criminal Justice Reform Award (2013) and the American Constitution Society’s David Carliner Public Interest Award (2014).

He is @PWPolicy on Twitter.
