Integrating Validated A Posteriori Probabilities on the Number of Contributors into Forensic Interpretation Pipelines for Full DNA Profile Interpretation will be presented at the 2019 NEAFS conference in Lancaster PA by Dr. Catherine M. Grgicak.
Here she will summarize the developmental validation of NOCIt – a software that renders the a posteriori probability distribution on the number of contributors to complex DNA mixtures – with a large-scale forensically relevant dataset. Notably, Dr. Grgicak shall demonstrate how the APP is used to calculate a full weight-of-evidence (log likelihood ratio or LR) without the need to designate that a particular NOC explains the evidence.
Dr. Grgicak introduces forensic DNA data and the forensically relevant PROVEDIt DNA database to data researchers at Ireland’s SFI Centre for Research Training in Foundations of Data Science

OPEN FORUM: SCI 114 (Chemistry Conference Room).
On Thursday April 25th at 3pm, come see Amanda present her work on: DEVELOPING A FORENSICALLY RELEVANT SINGLE-CELL INTERPRETATION STRATEGY FOR HUMAN IDENTIFICATION.
In this work Amanda demonstrates that single-cell signal is fundamentally different than signal acquired from bulk-processing, signifying new interpretation constructs are needed for forensically relevant single-cell signal.
On Monday April 29th at 5pm, come see Laura present her work on: STABILIZING INFORMATION CONTENT IN DNA EVIDENCE FOR IMPROVED LAB-TO-LAB INFERENCE
Laura shows that the information content in forensic electropherograms (EPGs) can drastically be improved by applying a simulation-experimental based approach. She then applies these improved post-PCR laboratory parameters to optimize the pre-PCR process.
On Friday March 29, 2019, Dr. Grgicak will speak on topics related to Systems Thinking and the Impacts on Forensic Inference.
She shall summarize LFTDI’s work on the development of our computational systems which compute the a posteriori probability (APP) on the number of contributors (NoC) and the likelihood ratio (LR). Notably, she will highlight how the results from two computational systems may be combined in order to procure a complete weight-of-evidence. Last, she shall show how systematically optimizing the forensic laboratory process, using simulation, can improve LR outcomes and stabilize them across laboratories, improving inference outcomes nationally.
Gravenor Lecture Series Announcement
LFTDI acquires an Ion S5 and Chef NGS system for forensic applications. The technology will be used to build a dynamic model of the entire NGS pipeline, which will be used to optimize the NGS process for efficient and reliable forensic data generation in a cost effective manner.

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.
