About Me

My work in criminal justice stems from my firm belief that criminal justice involvement represents one of the most important social and racial justice issues of our time.  I am especially interested in how criminal justice research can directly inform criminal justice reform policies and how we can change the cultural narrative around crime and punishment in the US.
