Veterinary microbiology and zoonoses; clinical management of pig health and disease

RESEARCH

My research interests lie in the control of infectious diseases, primarily of pigs, that threaten food chain security in the developed and developing world. These threats to food security include animal-to-human infections that could be transmitted in food or directly (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, and social sciences, aiming towards better prevention and management of infectious and zoonotic disease.

CLINICAL

I am a Diplomate of the European College of Pig Health Management and provide clinical expertise to pig producers and related organisations around the world.

POLICY

I contribute to UK government policy though membership of the following groups:

TEACHING

I organise the 5th year course: Pig Medicine and support teaching in the 4th year course, Veterinary Public Health.

Research

Current and recent research is focused on application of new molecular technologies to entrenched endemic diseases of food animal species - particluarly pigs (also my clinical interest). This includes whole genome sequencing and functional genomic studies of bacterial respiratory pathogens of pigs to identify new diagnostic / epidemiological tools, new vaccine candidates and characterisation antibiotic resistance (Streptococcus suis and Haemophilus parasuis).
