“The Role of Race/Ethnicity in Criminal Justice Adjudications,” Co-Principal Investigator with N. Nicosia. National Institute on Drug Abuse (NIDA), 2008-2011.
The major goals of this project are to examine the adjudication of drug offenders in California to determine the extent to which race/ethnicity has played a role in final disposition and referral to drug treatment. The study considers temporal and geographic patterns in disparities at each stage of the adjudication process within a single state subject to the same rule of law. Finally, by considering the impact of restorative justice policies, such as drug courts and diversion, on the processing of drug offenders by race/ethnicity, this project will assist policymakers with efforts to reduce disparities in the criminal justice and treatment system.

“Treatment Effects on Desistance From Youth Violence,” Principal Investigator. Centers for Disease Control and Prevention (CDC), 2005-2009.
The major goals of this project to identify the pathways to desistance from crime and violence as the sample enters young adulthood; identify the psychosocial events during young adulthood that are associated with desistance pathways for this cohort; to examine whether any direct effects of treatment on desistance from crime and violence exist; and test if treatment effects on desistance are mediated by treatment effects on key developmental events of young adulthood.
“Impact of Light Rail on Physical Activity & BMI,” Principal Investigator. National Institute of Environmental Health Sciences (NIEHS), 2005-2008.
