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.

Variability in Blow-Fly Development - Research and Implications for PMI Practice

Noviembre 0218

Dr. Leon Higley’s work to characterize blow-fly species indicates that there is variation within a single population--the bell curve is wide. Dr. Higley will share his research and discuss how the science is challenging some notions about PMI analysis.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on November 7, 2018.

Effective Leadership Communication: Why it Makes or Breaks Leading Change

Enero 0202

Effective leadership communication plays a vital role in promoting meaningful change within an organization. This presentation explores key principles such as “modeling the way”, “inspiring a shared vision”, and “start with why”. Vision-driven communication requires crime laboratory supervisors to utilize various communication tools while they act as a driving force within the organization, leading their teams to success.

Statistical Genetics and the Mechanisms of Probabilistic Genotyping

Mayo 0019

Probabilistic genotyping is a tool that uses computing power to aid in the identification of possible genotype sets within DNA typing results and to calculate likelihood ratios to estimate evidentiary weight. In this installment of Probabilistic Genotyping of Evidentiary DNA Typing Results, we will detail the background and principles of biostatistical analysis, to include match probabilities, likelihood ratios and other specific topics aimed at furthering understanding of the statistical basis of probabilistic genotyping.

Occurrence and Utility of Latent Print Correspondences That Are Insufficient for Identification

Febrero 0018

This event brought together practitioners and researchers to enhance information-sharing and promote collaboration among the impression, pattern, and trace evidence analysts, law enforcement, and legal communities.

The symposium was presented by the NIJ Forensic Technology Center of Excellence January 22-25, 2018.
