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.

Frank Wendt, Ph.D. Candidate
Frank is a Biomedical Science Ph.D. Candidate under the mentorship of Dr. Bruce Budowle. He received his Bachelor of Science degree in Forensic Science, with a concentration in biology, from The Pennsylvania State University in 2013. His undergraduate research projects involved understanding how microorganisms thrive in, and contribute to, the sub-zero temperature ecosystems of Siberian, Antarctic, and Pennsylvania cold trap permafrost (Dr. Corien Bakermans), evaluation of rapid DNA technologies for field-forward applications (Dr. Mitchell Holland), and applications of massively parallel sequencing (MPS) to mitochondrial DNA, specifically for detecting transmission of heteroplasmy in maternal lineages (Dr. Mitchell Holland). Frank’s doctoral work in the Budowle Lab focuses primarily on in silico characterization and MPS interrogation of full-gene regions of opiate absorption, distribution, metabolism, and excretion (ADME) and analgesic response pharmacogenes. Genetic variations (e.g., single nucleotide polymorphisms, insertion/deletion polymorphisms, gene transversions, and/or copy number changes) in these genes produce phenotypic variation that may contribute to addiction, overdose, and even death and are an emerging concern for the personalized healthcare, forensic genetics, and pharmaceutical communities. The overall goal of his doctoral work is to develop and evaluate the utility of a comprehensive (full-gene) and combinatorial (multi-genic) metabolizer phenotype for molecular autopsy of deceased, tramadol-exposed Finns using genes encoding proteins responsible for various portions of the opiate ADME and response pathways. Frank also has been involved in collaborative side projects addressing topics of MPS and capillary electrophoresis assay development, Native American population genetics, design and implementation of MPS data analysis software, application of tandem mass spectrometry and statistical methods to screening for ignitable liquids in fire debris, and identification of opioid polypharmacy combinations of clinical and public health interests. Frank plans to defend his dissertation in Summer 2018.
