My current research focus is at the intersection of criminal career, recidivism and reentry, and criminal justice policies. I am interested in applying statistical and econometrical methodology to better understand the dimensions of a criminal career: onset, continuity, and desistance, and more importantly, how the dimensions interact with the criminal justice system and policies.

I am also interested in the application of social network analysis to the study of crime. There has been a surge of interest in social network analysis among social scientists, and criminologists have produced promising direction in the application to criminological and criminal justice problems. I believe that social network analysis, which explicitly considers individuals and groups embedded in various social relations, can greatly complement the more conventional attribute-based research in criminology.
