David Engelthaler Ph.D.

David Engelthaler is the Co-Director and Associate Professor of Pathogen Genomics Division at TGen North. TGen North focuses on pathogen genomics with a specific mission to advance clinical medicine, public health and biodefense. Dave is also the Executive Director of the Southwest One Health Collaborative, Director of the TGen North Clinical Laboratory and Co-Director of the AZ COVID-19 Genomics Union. Dave has overseen the rapid development of TGen’s FDA-allowed COVID-19 diagnostics tests, the standing up of a federally-licensed COVID diagnostic laboratory, and the institution of the AZ COVID sequencing reference laboratory - all in support of the Arizona’s public health and healthcare response. Dave is also overseeing or participating in multiple COVID research projects, from assessing the impact of COVID on HIV populations, to providing testing for clinical trials of new drugs, to environmental analyses.

Just prior to the COVID-19 pandemic, Dave was overseeing research projects involving advancing our understanding of multi drug resistant infections; development of novel genotyping techniques for genomic epidemiology and microbial forensics; fungal epidemiology and phylogenetics; and more. A major focus of this works involves adapting and advancing the use of next-generation sequencing tools for infectious disease research and health care. Dave also oversees the application of the above research in real-life disease outbreak investigations, both natural and man-made. Recently, Dave led investigations involving invasive group A Strep in the Southwest, Cryptococcosis emergence in the Pacific Northwest, a multi-state fatal fungal meningitis outbreak associated with contaminated medical products and many other disease investigations.

Dave is leading teams that have developed revolutionary techniques to detect extremely low-level subpopulations of resistant Mycobacterium tuberculosis in patients, weeks to months before current tests can detect resistance. Similar approaches are being applied to develop a next generation of test for hospitals and clinicians to rapidly identify critical multi-drug resistant organisms that result in tens of thousands of deaths in the US every year. 

Prior to joining TGen, Dave was the State Epidemiologist for Arizona, at the Arizona Department of Health Services, where he was responsible for coordinating outbreak investigations and disease research activities state wide. From 2000 to 2005, Dave was also the Arizona Biodefense Coordinator, responsible for coordinating all state-wide activities regarding public health emergency preparedness and response, including response activities to suspect biothreat events, such as the suspicious powders that were seen following the anthrax letter attacks. He also served as state-wide coordinator for Pandemic Influenza and other public health emergency response activities. Prior to 2000, Dave was a biologist for the Federal Centers for Disease Control and Prevention, in Fort Collins, Colorado, where he conducted research on highly infectious diseases like plague and tularemia.

Dave received a Ph.D. in Biology from Northern Arizona University with a focus on genomic epidemiology and a Master’s Degree in Microbiology from Colorado State University, where he studied host-vector-pathogen dynamics.
