Research Interests

Aaron's current research portfolio includes research on street lighting, "precision policing," off-duty and overtime work by police officers and the relationship between legal access to alcohol and sexual assault victimization.  His past research has considered the effect of police manpower on crime and imprisonment and the relationship between crime and immigration enforcement, among other topics. He is also interested in research that advances social science research methods and has written on topics such as measurement errors in observational data, measuring spatial crime concentration and the empirical implications of administrative data linking.  Aaron is an affiliated researcher at the University of Chicago Crime Lab.
