Keramet Reiter studies prisons, prisoners’ rights, and the impact of prison and punishment policy on individuals, communities, and legal systems. She uses a variety of methods in her work — including interviewing, archival and legal analysis, and quantitative data analysis — in order to understand both the history and impact of criminal justice policies, from medical experimentation on prisoners and record clearing programs to gun control laws and the use of long-term solitary confinement in the United States and internationally.
