Our research interests include: 1) advanced molecular methods for identification and subtyping of pathogenic organisms; 2) mechanisms of antimicrobial resistance and resistance transfer among bacteria. 

We perform whole genome sequencing to better understand molecular evolution and ecology of Salmonella, Shiga toxin-producing E. coli and other foodborne pathogens, and participate in GenomeTrakr network
(https://www.fda.gov/food/whole-genome-sequencing-wgs-program/genometrakr-network).
The initiative holds the potential to dramatically improve public health globally.

We also conduct research on multidrug-resistant foodborne pathogens to elucidate the molecular mechanisms of antimicrobial resistance.  Our work has helped determine associations of antimicrobial use in animal production environments with subsequent spread of resistant bacteria throughout the food chain.

Solving food protection problems locally, regionally, and internationally
