Staff & Volunteers

The Prison Policy Initiative's accomplishments are those of a much larger organization. Thanks to your support, we've added staff and our capacity to help make social change is growing quickly. Learn more about our current and past staff.


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.

She is also the co-author of Mass Incarceration, COVID-19, and Community Spread, which shows how mass incarceration and the failure to reduce prison and jail populations quickly led directly to an increase in COVID-19 cases, not just inside correctional facilities, but in the communities and counties that surround them.

In addition to these reports, Wendy conducted the Prison Policy Initiative's frequently-cited 2017 50-state surveys of wages for prison labor and medical copays charged to incarcerated people, and she frequently contributes shorter briefings on recent data releases, academic research, women's incarceration, pretrial detention, probation, and more.

Part-time staff

Bernadette Rabuy Bernadette Rabuy is a Senior Policy Analyst at the Prison Policy Initiative. Bernadette’s research has focused on prison and jail visitation and making key criminal justice data accessible to the public. She co-authored the first comprehensive national report on the video calls industry, Screening Out Family Time: The for-profit video visitation industry in prisons and jails, which has played a key role in protecting in-person family visits in Portland, Oregon, California, and Texas. Her research was also essential to the movement that led the largest video call provider, Securus, to end its automatic bans on in-person visits.

Bernadette is passionate about making the criminal justice system easier to understand and therefore reform. She co-authored the report, Detaining the Poor: How money bail perpetuates an endless cycle of poverty and jail time, which finds that the median bail bond amount in the U.S. represents eight months of income for the typical detainee.

In her day job, Bernadette is a Trial Attorney in the Homicide & Major Crime Defense Unit at New York County Defender Services. She is grateful to the following organizations that have allowed her to become a stronger advocate: Southern Poverty Law Center, Prison Law Office, National Council on Crime and Delinquency, VOTE, and Californians United for a Responsible Budget. She is a graduate of University of California, Berkeley and University of California, Los Angeles (UCLA) School of Law. You can say hi at @BRabuy.
