Title: Machine Learning and Ballistics: a Data Analytics Project in Partnership with the New Jersey State Police


MBS students and Christie Nelson have partnered with the NJ State Police Forensics Lab on a ballistics data analysis project, utilizing machine learning (predictive and unsupervised models), data visualization, descriptive data analysis, and data cleaning techniques. We utilized data from a few different ballistics databases like NIBIN and Gun-ops, and examined data around when ballistics crimes were committed, their location, those that have a weapon used in multiple incidents, and many other questions of interest to the NJ State Police. Analysis included questions such as: what is the duration (time) between linked shooting events, where is the next crime likely to occur, what kinds of weapons are used most frequently in crimes (and are there variations between weapons used once vs those used repeatedly), and more.

This work was most recently cited in an Aug 2018 report done by the National Crime Gun Intelligence Governing Board:

It was presented to the ATF, state and local law enforcement, a county prosecutor's office, the Police Foundation, the Center on Policing, and more (, and was separately was presented to NJ Ballistics Community of Interest working group meeting (May 2018).

Dr. Christie Nelson is an Assistant Research Professor at Rutgers University with a postdoc and Ph.D. from Rutgers University, a Masters from Columbia University in Operations Research, and a bachelors degree from Westminster College in Mathematics. She is a researcher with CCICADA, a Dept. of Homeland Security Center for Advanced Data Analysis, and currently has over 100 combined peer reviewed publications, book chapter, conference, workshop, and invited presentations. Her research includes partners such as the US Coast Guard, TSA, all major professional sports leagues, MetLife Stadium, the Federal Law Enforcement Training Center, and more.
