Her primary research interest is applying metagenomics and whole genome sequencing methods to better understand microbial communities associated with foods and surface water. Currently, she’s investigating the microbial communities in waters used in produce production and their associations with the presence of Salmonella enterica and other pathogens to improve food safety traceability.
