Rachel Oefelein is currently the Chief Scientific Officer at DNA Labs International (DLI). Additionally, Rachel is a PhD candidate with Griffith University located in Brisbane, Australia.
She received her MSc in Forensic Science from the University of Strathclyde, and her BS in Criminal Justice, with a Forensic Science Minor, from Loyola University of New Orleans. Rachel worked at the Armed Forces DNA Identification Laboratory (AFDIL) for nearly five years and previously interned at the Instytut Ekspertyz Sądowych, the Forensic Laboratory in Krakow, Poland.
Since joining DNA Labs International in 2014, Rachel has testified in 13 Florida counties, seven states and U.S. Territories, and five countries as an expert witness for both the prosecution and the defense in misdemeanor and felony trials, as well as William, Frye, Daubert, and Arthur hearings.
NEWER THAN NEW
Forensic DNA is on the cusp of a wave of new technologies. Forensic Investigative Genetic Genealogy (FIGG) sparked a fire of innovation throughout the community.
New chemistries and software packages are enhancing the type of evidence that can be considered for FIGG dramatically. Were you previously told your sample wasn't eligible for FIGG or didn't yield suitable results? That may have changed! Single nucleotide polymorphism (SNP) to SNP comparisons, long-range kinship comparisons using both traditional short tandem repeats (STRs) and SNPs, and complex mixture analysis are becoming a reality.
FIGG and kinship is not the only area seeing major technology and software releases in forensic DNA. STRmix and DBLR software releases aim to take a deeper dive into mixture analysis allowing comparisons of mixtures across different crime scenes, building of offender profiles from a combination of mixtures, and familial searching. With the increases of sensitivity in DNA testing, the questions have shifted from whose DNA is this to how did this DNA get here?
Evaluative reporting, which seeks to analyze some of these activity level hypotheses, is now being introduced as evidence in the United States. What is available now and what will be available in 2024? This presentation will dive into all of your newest options!
