The Center for Advancing Correctional Excellence (ACE!) is a research center in the Department of Criminology, Law, & Society at George Mason University in Fairfax, VA. We conduct collaborative and creative research to assist policymakers and correctional practitioners with using evidence-based practices and treatments. We work with our partners in crafting new policies focused on preventing criminal behavior instead of simply responding to it. ACE! is led by Director Faye Taxman, PhD, and Deputy Director Danielle Rudes, PhD. ACE! was founded in 2010 as a research center to bridge disciplines and bring together researchers, practitioners, and policymakers to grapple with issues that affect criminal justice and health systems. As part of the Department of Criminology, Law, & Society at George Mason University, ACE!’s goal is not only to conduct high quality research but to develop the next generation of researchers.
