David Mazeika (Professor M.) earned his PhD in criminology and criminal justice from the University of Maryland. While at Maryland he served as an advisor to the Cambridge University Police Executive Program, training police officers in Jaipur, India on geospatial crime analysis techniques. Prior to joining TCNJ, he served as a research analyst in the Washington DC Statistical Analysis Center, where he helped secure over $300,000 in grant funds from the Bureau of Justice Statistics. Working closely with the Metropolitan Police Department, DC Attorney General, DC Superior Court, Pretrial Services Agency, and the Department of Youth Rehabilitation Services, he completed a number of process and impact evaluations on juvenile and criminal justice programs including fugitive safe surrender, teen and truancy court diversion, victim-offender mediation, and electronic monitoring.

At TCNJ he studies the geographic distribution of crime to quantify spatial concentrations, locate crime hot spots, and identify patterns and risk factors predictive of crime. His work also focuses on policing and public policy, with an emphasis on laws, policies, and practices in New Jersey. Working closely with a reporter at the Asbury Park Press and ProPublica, along with a team of TCNJ students, this work has uncovered sexist physical fitness standards in NJ police academies, the limited utility and dangers of police vehicular pursuits, and problems with the way NJ selects/promotes police chiefs. His research on vehicular pursuits led, in part, to the state’s first update to their policy in over 10 years. Most recently he has started to explore ways police are funded and organized in NJ and the potential to consolidate and share police resources between municipalities.
