Research interests 

I joined SAC in June 2009 as a Laboratory Scientist. I currently provide technical support both in the laboratory and in the field for several research projects. Some recent projects are listed below.

Selected research projects

  • Estimation of AMR in archived faecal samples
  • Maximising the predictive power of different measures of antimicrobial resistance for clinical outcomes using clinical mastitis in dairy cows as an exemplar
  • FSA/FSS – E.coli O157 super-shedding in cattle and mitigation of human risk
  • DEFRA – Interventions to reduce E.coli O157 shedding in cattle prior to slaughter
  • FSA – Trial of visual inspection of fattening pigs from non-controlled housing conditions
  • FSA - Detection of sorbitol-fermenting verocytotoxin-producing Escherichia coli O157:H-
