General research interests include monitoring animal health and production, epidemiologic research methodology (particularly the use of multivariable methods for modelling animal health problems), clinical trials and studies of risk factors for animal health problems. Specific interests include gastro-intestinal parasites and udder health in dairy cattle and ISA in salmon (aquaculture).
