Research Interests

My research interests lie in the control of infectious diseases that threaten food chain security. These threats to food security include animal-to-human infections (zoonoses), over-reliance on antimicrobial drugs, reduced feed conversion efficiency, and compromised welfare. I try to combine my clinical interest in intensive pig production with multidisciplinary research that includes molecular and epidemiological approaches aiming towards better prevention and management of infectious disease. My current research is focused on application of new molecular technologies to entrenched endemic diseases of pigs. This includes whole genome sequencing studies of bacterial respiratory pathogens of pigs to identify new diagnostic and epidemiological tools (Streptococcus suis, Haemophilus parasuis, Actinobacillus pleuropneumoniae, and Mycoplasma hyopneumoniae). We are using a functional genomics method, transposon directed insertion site sequencing (TraDIS), and ex vivo respiratory organ culture systems to identify genes in S. suis and H. parasuis worthy of future investigation as vaccine candidates.

Through a Junior / Senior Clinical Training Scholarship Program (funded by Pfizer Animal Health) we also participate in a variety of applied clinical research projects involving representatives of the local pig industry.
