My research interests are focused on the microbial ecology of the gastrointestinal tract and the role of the complex gut microbiota in health and disease.
I have a particular interest in the isolation and characterisation of gut commensal bacteria of animal and human origin for use as probiotics for exclusion of gut pathogens. Mechanisms of competitive exclusion phenomena are being investigated with the objective of designing strains with improved functionality.
I am interested in identifying and characterising novel antimicrobials (including bacteriophage endolysins) that target gut pathogens such as Clostridium difficile and Clostridium perfringens, and the impact of these biomolecules on the gut microbial communities is another area of active research within my group.
The effect of dietary components on the gut microbial ecology and the importance of gut commensals in transformation of food bioactive molecules are being studied using in vitro model gut systems as well in vivo with human volunteers.
