Dr. Bruce Budowle, Professor & Executive Director

About Bruce

Dr. Bruce Budowle received a Ph.D. in Genetics in 1979 from Virginia Polytechnic Institute and State University. 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 diseases such as insulin dependent diabetes mellitus, melanoma, and acute lymphocytic leukemia.From 1983-2009, Dr. Budowle worked at the FBI Laboratory Division to carry out research, development, and validation of methods for forensic biological analyses. Dr. Budowle has contributed to the fundamental sciences as they apply to forensics in analytical development, population genetics, statistical interpretation of evidence, and in quality assurance. Some of his technical efforts have been: 1) development of analytical assays for typing a myriad of protein genetic marker systems, 2) designing electrophoretic instrumentation, 3) developing molecular biology analytical systems to include RFLP typing of VNTR loci and PCR-based SNP assays, VNTR and STR assays, and direct sequencing methods for mitochondrial DNA, and 4) new technologies; and 5) designing image analysis systems. 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 490 articles, made more than 580 presentations (many of which were as an invited speaker at national and international meetings), and testified in well over 250 criminal cases in the areas of molecular biology, population genetics, statistics, quality assurance, and forensic biology. In addition, he has authored or co-authored books on molecular biology techniques, electrophoresis, protein detection, and microbial forensics. Dr. Budowle has been directly involved in developing quality assurance (QA) standards for the forensic DNA field. He has been a chair and member of the Scientific Working Group on DNA Methods, Chair of the DNA Commission of the International Society of Forensic Genetics, and a member of the DNA Advisory Board. He was one of the original architects of the CODIS National DNA database, which maintains DNA profiles from convicted felons, from evidence in unsolved cases, and from missing persons. Dr. Budowles efforts over the past decade also have focused on counter terrorism specifically efforts involving microbial forensics and bioterrorism. Dr. Budowle was involved directly in the scientific aspects of the anthrax letters investigation and has been one of the architects of the field of microbial forensics. He has been the chair of the Scientific Working Group on Microbial Genetics and Forensics (hosted by the FBI), 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. He currently serves on other government working groups related to microbial forensics. He also has served on the Steering Committees or been a co-organizer for the Colloquia on Microbial Forensics sponsored by American Society of Microbiology, Microbial Forensics Meetings, hosted by DHS, held at The Banbury Center in the Cold Spring Harbor Laboratory, and a meeting on Microbial Evolution and Cutting Edge Tools for Outbreak Investigations, hosted by the Centers for Disease Control and Prevention. He has published a number of articles (see below) on microbial forensics on topics such as attribution, quality assurance, population genetics, next generation sequencing technology, and sample collection. His current efforts at UNTHSC continue to focus on the areas of human forensic identification, microbial forensics, and emerging infectious disease.

Angie Ambers, PostDoc



Dr. Angie Ambers received her Ph.D. in Molecular Biology from the University of North Texas (UNT) with an emphasis in forensic genetics and human identification. Her dissertation involved an investigation of methods (e.g. whole genome amplification, DNA repair) for improving autosomal and Y-STR typing of degraded and low copy DNA from human skeletal remains and environmentally-damaged biological materials. Dr. Ambers also has master’s degrees in Forensic Genetics from the University of North Texas Health Science Center and in Criminology from the University of Texas at Arlington. Her thesis research involved developing and optimizing a DNA-based multiplex screening tool for the separation of fragmented and commingled skeletal remains. Since 2005, Dr. Ambers has been an adjunct professor at the University of North Texas (teaching Genetics, Heredity, and Human Anatomy andPhysiology). In 2008 she developed the curriculum for a course inForensic Molecular Biology, in which she teaches DNA analysis/methodology to undergraduate students enrolled in the FEPAC-accredited forensic science certificate program. Prior to pursuing her doctorate, Dr. Ambers was lead DNA analyst and lab manager of UNT’s DNA Sequencing Core Facility, and during that time had the opportunity to work on various ancient DNA projects involving archaeological specimens from Greenland. Her latest work has involved DNA testing of various historical human skeletal remains, including those of an American Civil War guerrilla scout, several Finnish World War II soldiers, and unidentified late-19th -century skeletal remains discovered in Deadwood, South Dakota. Dr. Ambers is currently a postdoctoral fellow at the IAG, specializing in characterization and identification of historical and archaeological human skeletal remains.
