Xiangyu Deng is a Professor in the Center for Food Safety at the University of Georgia, part of the College of Agricultural and Environmental Sciences (CAES). His research focuses on genomic epidemiology, food microbiology, and bioinformatics, with a particular emphasis on Salmonella and Listeria species. He leads the Deng Lab, developing cutting-edge tools like SeqSero2 for rapid serotype prediction using whole-genome sequencing. His work integrates machine learning and next-generation sequencing to improve food safety surveillance and antimicrobial resistance monitoring.
Key research areas include global Salmonella transmission dynamics, mobile colistin resistance genes (mcr), and the impact of centralized poultry breeding on pathogen spread. Deng has secured grants from USDA NIFA and the Center for Produce Safety, and his lab's SeqSero2 tool is FDA-validated. He serves on AOAC International's Board of Directors and has advised multiple students, including Shaoting Li and Yingshu He, who now hold academic and industry roles.
Notable achievements include identifying the global spread of Salmonella Enteritidis via poultry trade, and pioneering quasi-metagenomics methods for pathogen detection. His lab's work is featured in Nature Food, Nature Communications, and Applied and Environmental Microbiology.
Recent projects explore genomic epidemiology of multidrug-resistant pathogens, machine learning applications in food safety, and microbial community analysis in agricultural systems. The lab collaborates internationally, with studies in Lebanon, China, and Syria addressing emerging antibiotic resistance threats.
