Research Interests: 

Professor Loeffler’s research examines the effects of criminal justice processes on life-course outcomes. He is currently studying the effects of criminal record expungement on employment outcomes and the effects of processing juveniles as adults on life-course outcomes. His research also examines a number of other measurement problems in criminology. These include the development of new methods for measuring crime displacement resulting from place-based interventions and new methods for measuring firearm use within community-supervised correctional populations.
