Key research themes
1. How do policy choices and sentencing practices causally influence incarceration growth and demographic disparities?
This body of research focuses on identifying the causal drivers behind the unprecedented growth in incarceration rates, particularly in the United States, and how sentencing policies and demographic factors interact to produce racial, ethnic, and age-based disparities. Understanding these policy effects is critical to inform reforms aimed at reducing mass incarceration and addressing social inequality embedded in penal practices.
2. What are the causal effects of different types and durations of correctional sanctions on recidivism rates?
This theme encompasses rigorous evaluations comparing correctional sanctions—including probation, intensive probation, jail, and varying lengths of imprisonment—and their relative impacts on recidivism. Clarifying which sanctions effectively reduce reoffending is vital for evidence-based policy, especially amidst debates over mass incarceration and criminal justice reform.
3. How do contextual and structural factors within the prison environment and post-release social conditions affect recidivism and health outcomes?
Beyond sentencing itself, this research area investigates how prison environmental factors (such as crowding) and post-release neighborhood economic conditions influence parole violations, substance use, and health, including accelerated aging. These studies link incarceration conditions and reentry environments with long-term outcomes, emphasizing the importance of prison quality and social context in recidivism and public health.
