My research examines measurement problems in criminology. Much of this work is focused on estimating the life-course consequences of contact with the criminal justice system. These consequences can include changes to the likelihood of employment, criminal recidivism, and mortality. I also work on developing measurement tools for difficult-to-observe criminal behaviors, such as illegal firearm use among community-supervised correctional populations.
