Presentations include:

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. 

This presentation explores a series of research studies aimed at assessing the accuracy, repeatability, and reproducibility of forensic pattern evidence examination decisions across various disciplines, including latent prints, firearms, shoeprints, and handwriting.  Key topics covered include a comprehensive overview of the design factors in these four large-scale research studies, as well as a response to common critical observations regarding the experimental design and the interpretation of results.
