Sarah Allard is a postdoctoral fellow for CONSERVE, a Center of Excellence at the Nexus of Sustainable Water Reuse, Food, and Health. Sarah began her research career as an undergraduate, investigating the pollination efficiency and diversity of native bees on watermelon fields in the mid-Atlantic. After receiving her B.A. in Biology from Haverford College in 2009, she began an ORISE fellowship in the Division of Microbiology at the FDA's Center for Food Safety and Applied Nutrition. At FDA, she participated in environmental sampling for foodborne pathogens, evaluation of a food safety biological control agent, and optimization of Salmonella detection methods from environmental samples. As a graduate student in Plant Science at the University of Maryland, she studied the influence of farming practices and environmental conditions on the lives of microbes, including foodborne pathogens, in the complex agricultural environment. As part of the CONSERVE team based in the UMD School of Public Health, she is primarily working to characterize the microbiomes of nontraditional irrigation water sources including surface water and reclaimed wastewater. She is passionate about working towards the adoption of agricultural practices that are microbiologically safe, environmentally sustainable, and economically viable.
