Three women have been named recipients of the highest honor bestowed by the United States government to outstanding scientists and engineers.

Presidential Early Career Award for Scientists and Engineers awardees are Agricultural Research Service scientists Heather Allen at the National Animal Disease Center in Ames, Iowa; Jo Anne Crouch at the Beltsville Agricultural Research Center in Beltsville, Maryland; and Sara Lupton, at the Edward T. Schafer Agricultural Research Center in Fargo, North Dakota.

Allen is a microbiologist and an international expert on antibiotic resistance gene ecology and swine gut microbial communities. Her work has contributed to scientific understanding of the effects of agricultural practices on foodborne pathogens and antibiotic resistance genes in food-producing animals. She discovered that swine gut microbiota harbor diverse antibiotic resistance genes regardless of the antibiotic treatment administered. Her studies also have defined the effects of antibiotics on the swine gut microbiome in ways that can be applied to humans as well as other hosts.

Crouch is a molecular biologist whose work has been key to understanding the global diversity of fungal pathogens that cripple horticultural plants, turfgrass and cereal crops. She has developed molecular markers, diagnostic assays, genome tools and taxonomic resources that are used to combat downy mildews, boxwood blight, dollar spot and other plant diseases threatening crops across the United States and worldwide.

Lupton, who is a research chemist, is internationally recognized for her research about the fate of chemical contaminants in cattle, swine and poultry as well as their byproducts, waste systems, and feed sources. Her contributions have informed decision-making by regulatory agencies and promoted consumer confidence in the food supply and domestic milk and meat production practices.
