SWGDAM Mission Statement

 

The Scientific Working Group on DNA Analysis Methods, known as SWGDAM, serves as a forum to discuss, share, and evaluate forensic biology methods, protocols, training, and research to enhance forensic biology services as well as provide recommendations to the FBI Director on quality assurance standards for forensic DNA analysis.

About SWGDAM

 

SWGDAM is currently comprised of dedicated forensic scientists, from international, federal, state and local forensic DNA laboratories as well as guests representing academia and other Federal agencies. These forensic scientists serve as the DNA technical leaders or Combined DNA Index System (CODIS) Administrators for their laboratories, and are able to offer the perspectives of practitioners in the areas of nuclear and mitochondrial DNA technologies. SWGDAM is also fortunate to have invited guests attend each meeting representing academia, other Federal laboratories and international agencies to provide their specific expertise in areas such as mitochondrial DNA, population genetics, statistics, and YSTRs.

The responsibilities of SWGDAM are: (1) to recommend revisions, as necessary, to the Quality Assurance Standards for Forensic DNA Testing Laboratories and the Quality Assurance Standards for DNA Databasing Laboratories; (2) to serve as a forum to discuss, share, and evaluate forensic biology methods, protocols, training, and research to enhance forensic biology services; and (3) to recommend and conduct research to develop and/or validate forensic biology methods. We hold semi-annual meetings in January and July and our Committees meet more frequently as issues arise.
