I am a diplomate of the European College of Veterinary Public Health (subspecialisation population health) and am an associate editor of the Elsevier journal Small Ruminant Research. 

Scientific objective:

  • My aim is to identify drivers behind pathogenicity and transmission of mastitis-causing bacteria
  • I do that by studying host-pathogen interactions using a methods from epidemiology, molecular biology and pathogen genomics
  • I have a specific focus on ruminant mastitis caused by Staphylococcus aureus and mastitis control in the developing world

Apart from research, I teach in the bachelor and master of Veterinary Medicine and in the postgraduate master ‘Veterinary epidemiology and economics’. My main subjects are (molecular) epidemiology, statistics, clinical reasoning and small ruminant health.
