Bio Gary Gackstetter, DVM, MPH, PhD.
Dr. Gackstetter is currently Professor and Vice Chair, Research; as well as Co-Director, Graduate Research & Practicum Programs at Uniformed Services University of the Health Sciences, F. Edward Hébert School of Medicine, Department of Preventive Medicine and Biostatistics, in Bethesda, Maryland. He teaches both medical and graduate students. He is a fellow of the American College of Epidemiology and a board-certified preventive medicine veterinarian (DACVPM), earning a Doctor of Veterinary Medicine, from Iowa State; a Master of Public Health, from Boston University; and a PhD in Epidemiology, from University of Minnesota. Since the early 1980’s, Dr. Gackstetter has been active in entry-level veterinary licensing assessments as an item writer, consultant to Professional Examination Services, Inc., and as the veterinary public health expert on the Examination Development Advisory Board of the National Board of Veterinary Medical Examiners (NBVME). He has also chaired the NBVME, and was the National Association of Federal Veterinarians designee for three consecutive 3-yr terms, on the new International Council for Veterinary Assessment (formerly the NBVME). Additionally, he is a current member of the Collaboration for Veterinary Assessments Governance Committee (CVAGC). A committee established as a result of the formal collaboration between the International Council for Veterinary Assessment and National Board of Medical Examiners. In 2005, he retired as a Colonel from the Air Force, after 26 years of service. His active duty assignments included operational public health positions, Associate Professor in the Biology Department at the US Air Force Academy, Chief Epidemiologist at Air Force Basic Training in San Antonio, a 3-yr Pentagon assignment in the Office of the Secretary of Defense-Health Affairs, and Director of Graduate Programs at USUHS. He has managed multi-million dollar research projects and published more than 60 scientific articles. His research interests include zoonoses, infectious disease transmission and control; biosurveillance; military force health protection; and illnesses among Gulf War veterans. From 2005-2015, Dr. Gackstetter was one of four Corporate Fellows and a Principal Scientist with Analytic Services, Inc. (ANSER). He was assigned to the Defense Threat Reduction Agency (DTRA), Advanced & Emerging Threats Division (2008-20015), where he focused on supporting a $50M basic sciences research program in a chemical-biological defense context. Other assignments, as an Analytic Services Inc. employee, included the Office of the Special Assistant to the Secretary of Defense, Chemical and Biological Defense, within the Under Secretary of Defense (Acquisition, Technology & Logistics) at the Pentagon (2005-07), and the acting Program Manager at the National Biosurveillance Integration Center within the Department of Homeland Security (2007-08). He remains active as a collaborator and former co-investigator for the Millennium Cohort Study—a longitudinal study that began in 2001, designed to investigate health outcomes of more than 200,000 Military Service members for at least 50 years.
