Historically, the predominant means of assigning statistical weight to many DNA mixtures in the U.S. has been the combined probability of inclusion, or CPI. Accordingly, many forensic DNA analysts, as well as attorneys and judges, are well-versed in the CPI as a match probability. In the fifth module of this workshop series devoted to probabilistic genotyping, the presenters will help DNA analysts and legal professionals understand degrees of statistical weight and properly communicate likelihood ratios and their meaning. The SWGDAM recommendations for reporting likelihood ratios will be discussed, along with an explanation of the empirical basis for its verbal scale that may be used in reports and testimony along with the likelihood ratio. Participants’ ears will also be tuned to lines of questioning that could lead to a fallacious statement about the statistic.
This webinar is part 5 of of the Probabilistic Genotyping Of Evidentiary DNA Typing Results Webinar Series and was presented by the NIJ Forensic Technology Center of Excellence on June 8, 2019.

The Scientific Working Group on DNA Analysis Methods (SWGDAM) and other bodies have published guidelines that specify empirical studies to be performed to assess reliability, identify limitations and develop suitable usage conditions for probabilistic genotyping systems. In this installment of the web series Probabilistic Genotyping of Evidentiary DNA Typing Results, we discuss the intent of each validation requirement and provide examples of their execution, as well as resulting data and how they can be used to develop standard operating procedures within the forensic DNA testing laboratory.

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.

Based on the review of various forms of STR typing results and factors that impact the presence or condition of DNA on evidence, instructors in this installment of Probabilistic Genotyping of Evidentiary DNA Typing Results lay a foundation for the interpretation of forensic DNA typing results. The session will begin with background information on forensic DNA analysis, including terminology and mechanisms, to help all participants comprehend the material covered in this series. A retrospective view of approaches to interpretation and statistical analyses will be reviewed for the purpose of understanding the origin of strategies, methods, issues and solutions that comprise the history of forensic STR testing.
This webinar was presented by the NIJ Forensic Technology Center of Excellence. It is module 1 of the Probabilistic Genotyping Of Evidentiary DNA Typing Results Webinar Series.

In this webinar, the presenter will cover key components of successful onboarding in a crime lab, including setting employee expectations and making the employee feel like part of the team. The presenter will go over an onboarding checklist so you can devise one that suits your agency’s needs. Lastly, the presenter will discuss how successful onboarding can get the new employee “fired up” and increase employee engagement overall.
