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.

Just Navigating Reentry using Peer Support
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.
Let’s Talk About Stats
In this fireside chat, session six of the the Foundational Statistics for Forensic Toxicology series, panelists include practitioners and experts in forensic toxicology, and subject matter experts for the application of statistics in forensic toxicology. Join us in a dynamic and engaging session to explore common frustrations and challenges experienced in the laboratory, providing participants with valuable insights and practical solutions.

Just Increasing Access To Drug - Checking Services
In episode four of our community based solutions for Substance Use Challenges season, Just Science sits down with Doctor Nabarun Dasgupta, pharmacoepidemiologist and senior scientist at the University of North Carolina Injury Prevention Research Center, and Erin Tracy, research chemist in the University of North Carolina Injury Prevention Research Center, to discuss their unique approach to providing drug checking services on a broad scale.
Calculation of Type A Data from Control Data for Measurement Uncertainty
Session five of the Foundational Statistics for Forensic Toxicology series will incorporate concepts from earlier sessions and focus on the practical application of control data in estimating Measurement Uncertainty (MU). Rather than a discussion about how to calculate the MU, this session provides practical examples to demonstrate the key elements of the statistical process. Participants will learn how to incorporate control data into MU estimation by leveraging statistical techniques aimed at quantifying the uncertainty associated with measurement processes.

Just Wastewater Drug Surveillance in Kentucky
In episode three of our Community Based solutions for Substance Use Challenges season, Just Science sits down with Doctor Chris Delcher, associate professor in the Department of Pharmacy Practice and Science and director of the Institute for Pharmaceutical Outcomes and Policy at the University of Kentucky, to discuss how his team tracks community drug use through wastewater analysis. Much like analyzing a urine sample to determine what drugs an individual is using. Analyzing wastewater from a community offers insight into drug trends across an entire region of people.
Quantitative Analysis Method For Tetrahydrocannabinol Isomers
Of recent, forensic toxicology laboratories have been grappling with the emergence of tetrahydrocannabinol isomers within biological specimens. Traditional methodologies are often inadequate in the separation of Δ9-tetrahydrocannabinol and Δ8-tetrahydrocannabinol, which are the most common isomers identified in forensic testing.

FITS—Functional Implementation of Thorough and Systematic Approaches for Fracture Examinations
This webinar describes a simple and systematic method for comparing fracture fits using standardized qualitative and quantitative criteria. An extensive database of nearly 9,000 samples of duct tapes, automotive polymers, and textiles is used to estimate performance rates and strengthen the scientific foundations of fracture fit determinations. Also, the consistency of results from inter-laboratory studies shows the utility and reliability of the proposed approach.

Just Improving Forensic Toxicology Testing in DC
In episode one of our Community Based Solutions for Substance Use Challenges season just sat down with Doctor Samantha Tolliver, Chief Toxicologist for the District of Columbia Office of the Chief Medical Examiner, or DC OCME, to discuss how their agency uses their Bureau of Justice Assistances Comprehensive Opioid Stimulant and Substance Use Program, or COSSUP, funding to improve their drug testing and analysis processes.
Use of Controls and Other Control Chart Elements
In this fourth session of the Foundational Statistics for Forensic Toxicology series, we address common challenges, misconceptions, and questions encountered in day-to-day forensic toxicology laboratory settings related to statistics. Participants will gain insights into the practical application of statistical concepts and terminology in quality control and control charting, including trends and outliers. Furthermore, participants will learn about data interpretation, distinguishing between results that occur due to statistical significance and those the occur due to random variation.

Statistical Tests and Hypothesis Testing
This third session of the Foundational Statistics for Forensic Toxicology series explores hypothesis testing, a fundamental concept in statistical analysis, and its applications in forensic toxicology. Participants will gain an understanding of the different types of statistical tests, their respective applications, and how they can be utilized to uncover meaningful insights from toxicological data.
