Forensic and Investigative Sciences

Description

Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.  

NIJ’s forensic science research and development program focuses on basic and applied scientific research with the intent to:

  • Direct the findings of basic scientific research in broader scientific fields applicable to forensic science.
  • Apply forensic science research to the development of highly discriminating, accurate, reliable, cost-effective, rapid methods for the identification, analysis and interpretation of physical evidence.
  • Expand the scientific basis of forensic methods.
  • Produce useful materials, devices, systems or methods that have the potential for forensic application.
  • Increase the body of knowledge to guide and inform forensic science policy and practice.

The Forensic Examination and Comparison of Plastic Garbage Bags

August 2024

Plastic bags are present in many criminal cases. Analyzing these bags in a forensic case can sometimes identify the manufacturer. More importantly, forensic comparison of bags from a known box or other known source can determine whether the bag could have originated from that source. This webinar discusses the manufacturing process, class and randomly acquired characteristics, examination techniques, and comparisons between questioned and known bags. The final segment includes a discussion of recent research in this area, followed by a question-and-answer period.

Just Public Health and Safety Data Sharing in Georgia

August 2024

In the final episode of our Community Based solutions for Substance Use Challenges season Just Science sits down, Kristen Lee, substance use program coordinator at the Georgia Criminal Justice Coordinating Council. Lizann Roberts, executive director of the Coastal Georgia Indicators Coalition. And Tara Jennings, strategic planning administrator for Chatham County government, to discuss their COSSUP funded Community Data platform, which helps connect health and justice data for an individual so that first responders can best meet their needs.

Evaluating a Statistical Method for Comparison of Mass Spectra of Novel Psychoactive Substance

July 2024

Identification of novel psychoactive substances (NPS) based on comparisons of electron-ionization (EI) mass spectra continues to pose challenges in seized drug analysis. In this webinar, a method to statistically compare EI mass spectra is described, and an application of the method to distinguish several structural and positional isomers of NPS analogs are demonstrated.

This webinar was hosted by the NIJ Forensic Technology Center of Excellence on July 25, 2024. 

Just Navigating Reentry using Peer Support

July 2024

In episode five of our community based solutions for Substance Use Challenges season Just Science sits down with doctor Nicole Swiderski, New Jersey path to recovery grant manager and Jass Pelland, New Jersey Path to Recovery program manager to discuss how the New Jersey State Parole Board's 2021 Comprehensive Opioid Stimulant and Substance Use Program Award is supporting peer recovery and other services that help individuals with a substance use disorder navigate reentering the community after release from prison.
