- Animal health in all species, with a particular emphasis on the epidemiology of disease occurrence. My teaching includes elements of basic veterinary immunology, parasitology, microbiology, epidemiology, pathogenesis, diagnosis and disease control.
- Small ruminant production. I am interested in sheep/goat production systems worldwide and have been involved in research into and under a range of such systems.
- I also have a background in sheep/goat reproduction and continue to enjoy teaching in this area. I am particularly interested in the evolution of reproductive seasonality and the diversity of reproductive strategies employed by sheep and goats.
In the past few years my main research interests and areas of active work have included:
- Molecular diagnosis, epidemiology and control of Marek's disease in chickens. I am particularly interested in the ongoing evolution in virulence of the Marek's disease virus and the factors driving this.
- Integrated parasite management (IPM) in sheep. The sustainable management of parasites, particularly gastro-intestinal nematode (worm) infections is complex challenge given the widespread resistance to anthelmintic chemicals amongst sheep worms and the large part of the lifecycle spent in the environment rather than in the host. Understanding the free-living ecology of the main parasites is a key component of developing effective IPM.
- Improved sheep meat production systems in India, including utilization of the Booroola fecundity gene (FecB) to improved reproductive rate in Indian native breeds of sheep.
- Measurement of the infective virus status of chicken litter and methods for reducing viral pathogen load in litter between batches of broilers.
