Cybergenetics presents TrueAllele® solution at international NIST meeting

Washington, DC

The National Institute of Standards and Technology held an International Symposium on Forensic Science Error Management: Detection, Measurement and Mitigation in Washington, DC. Cybergenetics scientist Dr. Mark Perlin gave a talk on "Objective DNA Mixture Information in the Courtroom: Relevance, Reliability and Acceptance." The narrated YouTube movie (live audio & slides) is viewable from Cybergenetics website.

The talk begins with Bayes law as the way to update belief based on data. Dr. Perlin described DNA mixtures and STR mixture data. He showed how TrueAllele objectively infers genotypes from data using Bayes law, and then compares them without bias to calculate match statistics. Legal relevance and reliability issues were discussed. The mixture evidence example came from a Baltimore trial, where TrueAllele was used to help convict Maryland rapist Nelson Clifford.
