Staff
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.
Aleks Kajstura, JD, Legal Director. Aleks has worked with the Prison Policy Initiative in various capacities since 2003, and has been our legal director since 2009.
A 2008 graduate of the Benjamin N. Cardozo School of Law, Aleks played a central role in building the Prison Policy Initiative’s campaign against prison gerrymandering, including her publication, Prison Gerrymandering in Massachusetts: How the Census Bureau prison miscount invites phantom constituents to town meeting. Aleks has also led the organization's work on its second major issue, sentencing enhancement zones, authoring The Geography of Punishment: How Huge Sentencing Enhancement Zones Harm Communities, Fail to Protect Children and Reaching too far: How Connecticut’s large sentencing enhancement zones miss the mark.
Aleks continues to shed light on other hidden aspects of mass incarceration, for example sparking a New York Times editorial by highlighting mass incarceration's impact on women in States of Women's Incarceration: The Global Context.
In her spare time, Aleks plays hockey, competes in triathlons, and serves on the Finance Committee for the Town of Sunderland.
Wendy Sawyer is the Research Director at the Prison Policy Initiative. Wendy earned a Master's in Criminal Justice from Northeastern University and a Bachelor’s in Afro-American Studies from the University of Massachusetts. Before joining the Prison Policy Initiative, she worked as an investigator for the Civilian Complaint Review Board in New York City and as a research associate for Northeastern's Institute on Race and Justice.
Wendy is the author of numerous reports, including Mass Incarceration: The Whole Pie 2024, which gives the big picture of mass incarceration in the United States. 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.
She's also authored or co-authored reports on youth confinement, the misuse of police and jails to respond to social problems, gender disparities in incarceration, and probation fees. 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.

She is also the co-author of States of Incarceration: The Global Context 2021 and has published blog posts on various topics, including how states' "good time" systems can reduce prison populations during the pandemic, resources and data for organizations focused on policing, and why Black women are disproportionately affected by HIV.
