The goal of our research is to advance the understanding of genetic and environmental factors driving the:

  • persistence of foodborne pathogens in food systems;
  • expression of virulence factors;
  • development of antimicrobial resistance.

We use a precision food safety approach, including comparative genomics and metagenomics to generate the knowledge needed for the development of risk assessment tools and intervention strategies leading to a safer and sustainable food supply chain.
