Dr. Gregg Davis is a collaborating scientist at the the George Washington University Milken Institute School of Public Health. Dr. Davis uses genomic epidemiology to understand how the misuse of antibiotics in food animals affects public health. By analyzing the genomes of bacteria found in humans and food animals, he is quantifying the contribution of bacterial contaminants, such as Escherichia coli and Klebsiella pneumoniae, from retail meats to human urinary-tract infections. Dr. Davis is using whole genome sequencing to understand the emergence, epidemiology, and evolution of these and other colonizing opportunistic pathogens.
Previously, Dr. Davis’ research efforts were focused on understanding nickel transport in Helicobacter pylori and using interdisciplinary approaches to understand the distribution and evolution of high-molecular weight surface proteins in nontypeable Haemophilus influenzae. Dr. Davis received a bachelor’s degree in biology from Winthrop University and a master’s degree in biology from Northern Arizona University. Dr. Davis received his master’s degree in hospital and molecular epidemiology and doctoral degree in epidemiological sciences from the University of Michigan.
