Senior Research Associate
Justice Policy Center
I seek to discover what works by applying social science research to answer timely policy and practice questions of importance to the field of criminal justice. This often entails formative evaluation approaches which seek to examine implementation fidelity and providing guidance to those implementing innovative programs as part of the research process.
