In her workshop (Sept 24, 2018) at ISHI 29, Dr. Grgicak chairs a workshop demonstrating why a systems thinking approach to validation positively impacts forensic mixture interpretation outcomes. Dr. Grgicak describes what Systems Thinking is, how the PROVEDIt DNA Database came to be, and how her background in physical chemistry drives her research.
Monday September 24th, 2018 // 8:30 am – 5:00 pm
Drs. Grgicak and Lun along with Sarah E. Norsworthy publish an article entitled “Determining the number of contributors to DNA mixtures in the low-template regime: Exploring the impacts of sampling and detection effects” in Legal Medicine (DOI: https://doi.org/10.1016/j.legalmed.2018.02.001).
We show that capturing all of the information has positive impacts on inference while allele counting methods lead to underestimations.
The Forensic Technology Center of Excellence (FTCoE) will assist the National Institute of Justice (NIJ) in hosting the annual NIJ Forensic Science Research and Development (R&D) Symposium on February 20th, 2018 at the 70th Annual American Academy of Forensic Sciences (AAFS) meeting in Seattle, WA. The NIJ Forensic Science R&D Symposium is a free and open meeting where attendees learn about NIJ-funded research across a variety of forensic science areas.
Dr Grgicak will present LFTDI’s work pertaining to ValiDNA in a talk entitled
? Production of High-Fidelity Electropherograms Results in Improved and Consistent Match-Statistics: Standardizing Forensic Validation by Coupling Laboratory Specific Experimental Data with an In Silico DNA Pipeline
We modify our full in silico DNA pipeline to focus on resolving signal-to-noise within the single-copy regime.
The paper describes system design and ways in which the system can be implemented into forensic DNA validation and optimization.
Lauren Alfonse, Jennifer Sheehan and Catherine Grgicak will present our most recent work at the upcoming NEAFS 2017 conference.
Lauren presents her work on CleanIt: An automated artifact filtering macro; Jennifer delves into double-back stutter; and Catherine introduces ReSOLVIt.
