Dr. Looft is a Research Microbiologist in the Food Safety Enteric Pathogens research unit at the USDA-National Animal Disease Center in Ames IA. He completed his BS and MS at Bowling Green State University, Bowling Green, OH, and his PhD at Iowa State University, Ames, IA, where he studied swine microbiomes and the effects of antibiotic feed additives on intestinal microbial populations. He currently oversees a research program focused on defining the ecology of antibiotic resistance genes in the poultry microbiome, succession of the avian microbiota after hatch, and interaction between Campylobacter and the intestinal environment. In addition, Looft participates in education efforts as adjunct assistant professor in the Veterinary Microbiology dept. at Iowa State University. Through these efforts, Dr. Looft seeks to improve antibiotic stewardship by modulating intestinal microbiomes to improve animal health.
