At the International Symposium on Human Identification (ISHI) in Minneapolis, MN on September 26, 2016, the NIJ’s Forensic Technology Center of Excellence (FTCOE) presented at a workshop that provided attendees with a unique opportunity to learn best practices to implement massively parallel sequencing (MPS) into a typical forensic laboratory workflow. Supported by the FTCOE, University of North Texas Health Science Center, and North Carolina State University, an immersive and interactive virtual simulation tool was showcased that guides DNA practitioners through three commercially available forensic laboratory processes amenable to two MPS instruments. Attendees were given the opportunity to virtually employ laboratory protocols as well as analyze forensically relevant genetic loci through commercially available and third-party software applications.
► Despite various workshops and presentations, a substantial barrier to the adoption of MPS technology is bridging the knowledge gap between the laboratory bench workflow and the theoretical basis of the MPS chemistry. Through the developed interactive simulation tool, attendees were able to make the connection between the chemistry of MPS (MID design, bead manipulation, emulsion PCR, etc.) with respect to the molecular biological mechanisms of the technologies (bridge amplification, adaptor ligation, etc.). Additionally, attendees learned how these technologies are both similar and distinct from currently employed forensic protocols.
► Attendees navigated through the physical workflow of the Promega PowerSeq™ (STR) kit, the Illumina ForenSeq™ (STR, Y-STR, SNP) kit, and the Life Technologies AmpliSeq™ mtDNA kit. This exercise included immersive and interactive virtual demonstrations through the simulation tool of how to load onto the Illumina MiSeq™ (Powerseq™ and Forenseq™) and the Ion Torrent (AmpliSeq™) platforms. By demonstrating multiple technologies on two platforms, a more comprehensive experience was provided so that the attendees would have a better foundation on which to select the best platform to meet their agency’s needs and thereby further facilitate adoption.
► Attendees also learned how to analyze real data obtained from MPS technologies through vendor and third-party software applications. The instructors lead informative and engaging discussion on the bioinformatics processes of sequence data analysis (FASTA, FASTQ, PHRED quality scoring, etc.), and attendees were exposed to various software applications, including Illumina Universal Analysis Software package, STRait RAZOR, and HIrisPlex. Participants learned how MPS may provide additional mitochondrial DNA information on a sample of interest beyond what Sanger Sequencing may provide. Additionally, the end-user learned how other forensic markers of interest (SNPs) can be exploited to provide additional information which is not possible with current forensic genetic markers.

From 1979-1982, Dr. Budowle was a postdoctoral fellow at the University of Alabama at Birmingham. Working under a National Cancer Institute fellowship, he carried out research predominately on genetic risk factors for such diseases as insulin dependent diabetes mellitus, melanoma, and acute lymphocytic leukemia. From 1983-2009, Dr. Budowle was employed at the FBI Laboratory Division and carried out research, development, and validation of methods for forensic biological analyses. Dr. Budowle has worked on laying some of the foundations for the current statistical analyses in forensic biology and defining the parameters of relevant population groups. He has published more than 485 articles, made more than 550 presentations, and testified in well over 200 criminal cases in the areas of molecular biology, population genetics, statistics, quality assurance, and forensic biology. He has been a chair and member of the Scientific Working Group on DNA Methods, Chair of the DNA Commission of the ISFG, and a member of the DNA Advisory Board. He was one of the architects of the CODIS National DNA database, which maintains DNA profiles from convicted felons, from evidence in unsolved cases, and from missing persons. Some of Dr. Budowle’s efforts over the last decade are in counter terrorism, primarily in identification of victims from mass disasters and in efforts involving microbial forensics and bioterrorism. Dr. Budowle was an advisor to New York State in the effort to identify the victims from the WTC attack. In the area of microbial forensics, Dr. Budowle has been the chair of the Scientific Working Group on Microbial Genetics and Forensics, whose mission was to set QA guidelines, develop criteria for biologic and user databases, set criteria for a National Repository, and develop forensic genomic applications. In 2009 Dr. Budowle became Executive Director of the Institute of Applied Genetics and Professor in the Department of Forensic and Investigative Genetics at the University of North Texas Health Science Center at Fort Worth, Texas.
