Meagan Cahill (she/her) is a senior policy researcher at the RAND Corporation. For nearly 20 years, she has been conducting research and evaluation in the areas of policing and improving police-community relations; at-risk and delinquent youth—with a special focus on youths’ social networks; gang violence; interpersonal violence, including sexual assault prosecutions and family violence reduction; crime and place; and community crime prevention. She currently leads an impact and process evaluation of NYPD's Neighborhood Policing philosophy and an effort to develop tools that communities can use to improve police-community relations. She is also research director for the National Collaborative on Gun Violence Research, overseeing the solicitation process and grants management, and conducting an evaluation of OVW’s Sexual Assault Justice Initiative, which works to improve sexual assault prosecutions in seven sites. In early 2018, she began an assessment of the combined effects of anti-violence efforts in two cities, Minneapolis and Durham (NC), funded by NIJ. Prior to joining RAND, Cahill spent over a decade conducting multi-site evaluations of anti-gang programs and studying youth gang networks and the gang desistance process at another research organization.
Cahill’s work employs spatial analytic methodologies for crime analysis using geographic information systems (GIS), basic social network analysis, and quantitative and qualitative methodologies. She received her Ph.D. in geography from the University of Arizona in 2004 and received a National Institute of Justice Dissertation Fellowship in 2003-2004.
