DNA Labs International’s quality assurance manager/senior DNA analyst, Rachel Oefelein, and laboratory supervisor/techincal leader, Alicia Cadenas, will be featured speakers on Forensic® Magazine’s webinar “From Training to Trial: A Reflection on Nearly Three Years of Probabilistic Genotyping.”

Deerfield Beach, Fla. (January 2018)DNA Labs International, a private forensic laboratory in Broward County, Florida, is pleased to announce that two of its employees will be featured speakers on the webinar “From Training to Trial: A Reflection on Nearly Three Years of Probabilistic Genotyping,” presented by Forensic® Magazine and sponsored by Promega, on Wednesday, Jan. 31, 2018 at 11:00 am EST. The webinar will offer expert information from DNA Labs International’s quality assurance manager/senior DNA analyst, Rachel Oefelein, and laboratory supervisor/technical leader, Alicia Cadenas. The webinar will be moderated by Michelle Taylor, editor-in-chief of Forensic Magazine.

Forensic science is on the cusp of change across not only the United States, but also the world, as increasingly more laboratories transition to analyzing and reporting DNA mixtures as a likelihood ratio (LR) utilizing probabilistic genotyping software systems.

In this webinar, Oefelein and Cadenas will focus on two key topics: training and implementation, as well as casework results and courtroom experiences, including:

  • The original training, validation and implementation of STRmix™, as well as the challenges and lessons learned with validation and implementation.
  • Probabilistic genotyping to analyze mixtures that may have previously been reported as inconclusive.
  • The effects of the implementation of STRmix software on DNA mixture analysis of profiles obtained from firearms, sexual assaults and other commonly mixed DNA samples.
  • The experiences encountered as these cases make their way through the court systems with adjustments to report writing, courtroom testimony and Daubert/Frye challenges.
