Laboratory Faculty & Staff

Bruce Budowle, Professor
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. Budowle’s 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.

When he is not working, Jonathan enjoys photography and the culinary arts.

Bobby LaRue, Research Assistant Professor
Bobby LaRue earned his PhD at the University of North Texas in 2010. His dissertation focused on the stress experienced by metazoans in low oxygen environments and the cell signaling pathways used to ameliorate the damage caused by these conditions. In 2010 he was awarded an Intelligence Community postdoctoral fellowship. His current research interests include small amplicon markers for human and tissue identification including SNPs, small INDELs, LINEs and SINEs, and methylation patterns. His ultimate goal is to be able to improve typing of degraded and low quantity samples. When not in the lab, Bobby enjoys spending time with his family and being outside.
Angie Ambers, Forensic Technologist
Although originally from Tennessee, Angie has lived in the Dallas-Fort Worth metroplex for over 15 years. She has a Master's degree in Forensic Genetics from the University of North Texas Health Science Center and another Master's in Criminology from U.T. Arlington.
