To reach our objectives, we are developing techniques for advanced forensic DNA mixtures analysis and interpretation. Currently, mixed DNA sample analysis faces many challenges in linking an individual to a crime scene or location and as a result, multi-contributor DNA samples provide limited information or are not analyzed. However, in environments faced by an expeditionary military force, evidence linking a group of individuals could be of monumental importance. There is an enormous wealth of unanalyzed intelligence information hidden within mixed DNA samples. This research will be achieved by statistical analysis of mixed DNA samples and the creation of software and algorithms to ultimately enable tracking, group identification, and probability analysis of individuals in the group. The basic concept for this novel group analysis has been rudimentarily studied using Monte Carlo techniques, but it requires further validation via the ingestion of experimental data, which will be provided through a concurrent experimental study. This study will result in a paradigm shift in the analysis and handling of mixed DNA and its collection. Prospective applicants should have a strong background in Informatics, Genomics, Mathematics, Numerical Methods, and/or Statistics. The strongest candidates will be comfortable with Matlab and DNA analysis.
