COVID-19 has had an enormous effect on the workforce, and not just in the areas of operations and logistics. Workplace schedules have been completely rearranged, work-life balance has been turned on its head from telework, and reduced “in lab” hours have caused strain on an already stressed workforce. In this webinar, you will hear from three experts in workplace wellness, particularly in forensic science. They will discuss the various stresses in forensic laboratories, including issues like vicarious trauma, and present strategies that leaders can use to mitigate the negative effects of stress on their employees and improve the overall wellness of their lab.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on March 29, 2021.

The primary focus of this presentation is to develop a better understanding of the fragmentation behavior of emerging synthetic drugs in different types of mass spectrometers. The goal is to assist practitioners in seized drugs and forensic toxicology with their understanding of current casework, and to help them more-readily identify new drugs as they emerge.

Touch DNA is a potentially powerful sample type for forensic casework, but is challenging to work with due to low quantity, variable deposition amounts, and fundamental questions regarding stability over time. In this webinar we describe best-practices and initial results related to comprehensive studies of the stability of touch DNA after exposure to different environmental conditions.

This webinar will discuss the analytical methodology developed and validated to identify and quantify novel synthetic opioids and traditional opioids in oral fluid. The presenter will also discuss targeted and non-targeted approaches using liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods for detection of fentanyl- and non-fentanyl related novel synthetic opioids. Additionally, this webinar with cover sample preparation techniques for isolating synthetic opioids with various chemistries and structures. Further, analytical challenges regarding sample preparation and chromatography will be considered.

This webinar seeks to describe how preemptive synthesis and characterization of potent psychoactive substances from the literature can aid forensic scientists in the identification of unknowns appearing in samples emerging from illicit markets. Additionally, the presenter seeks to provide understanding of how gaps in pharmacological knowledge of old drugs can be exploited to find new emerging synthetic drugs.

The NIJ Forensic Technology Center of Excellence hosted a panel of subject matter experts to discuss emerging methods for body fluid analysis. This webinar is in three sections:

1) Proteomics and its potential in high-throughput forensic laboratories.
2) Surface Enhanced Raman Spectroscopy and the rapid detection and identification of body fluids.
3) MicroRNA, mRNA, and the development of a microfluidic device used to detect and differentiate body fluids from an unknown sample.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on January 14, 2021.

Throughout the Probabilistic Genotyping of Evidentiary DNA Typing Results virtual workshop series, we have reviewed aspects of DNA mixture interpretation and have seen that probabilistic genotyping (PG) software can serve as a tool to assist the DNA Examiner in identifying possible genotype sets within a mixture and then calculating a likelihood ratio (LR). Approaches to modeling were shared by the developers of different PG software programs, followed by examples of internal validation studies and results. In this module, lecturers in the series return to address audience questions and delve deeper into special areas of interest related to probabilistic genotyping of forensic DNA evidence.

This webinar is part 8 of the Probabilistic Genotyping Of Evidentiary DNA Typing Results Webinar Series and was presented by the NIJ Forensic Technology Center of Excellence on July 17, 2019.

Has a person of interest contributed DNA to a mixture obtained from evidence? Is that DNA associated with a crime? Both are questions that cannot be answered with absolute certainty. This module of the Probabilistic Genotyping of Evidentiary DNA Typing Results workshop series addresses the uncertainty and limitations of probabilistic genotyping systems that are used to calculate likelihood ratios and infer genotype sets from DNA typing results. Probabilistic reasoning provides a means to characterize these results, given the unknown information in forensic evidence, the stochastic environment, and sources of variability. Instructors in Module 7 will explore strategies of interpretation and decision making in light of these and other variables, such as the uncertain number of contributors, and will share research on the impact of these variables on the likelihood ratio.

This webinar is part 7 of the Probabilistic Genotyping Of Evidentiary DNA Typing Results Webinar Series and was presented by the NIJ Forensic Technology Center of Excellence on June 26, 2019.
