My research has focused on the molecular epidemiology of zoonotic foodborne pathogens including non-Typhoid Salmonella, E. coli O157:H7 and other STEC, Campylobacter spp. and multi-drug antibmicrobial resistance in Salmonella and other Gram-negative bacteria. I am particularly interested in the use of genotyping methods to study transmission routes of zoonotic pathogens and their maintenance and dissemination in reservoir species. I am also interested in exploring the causes of antimicrobial resistance in bacterial pathogens.
The most important questions that I am concerned with include:
- How are pathogens transmitted among animals and from animals to humans?
- What are the most important routes of transmission?
- What are the determinants of antibiotic resistance?
We have found evidence that similar genotypes of Salmonella and Campylobacter are found in bovine and human populations.
