 My current research focusses on the treatment of opportunistic pathogens associated with pulmonary disease, more specifically those that persist to form chronic infections of the cystic fibrosis (CF) lung. Using manuka honey alone, and in combination with a range of therapeutic agents, we have shown excellent inhibitory efficacy against a range of CF pathogens, such as; Burkholderia, Pseudomonas, Stenotrophomonas, Achromobacter, and Staphylococcus to name but a few of the genera studied. Previous research has focussed on the conflict and cooperation of bacterial cells in mixed communities, the diversity of cells from a seemingly clonal population, and the spatial structure of small bacterial aggregates, and larger biofilms.  Further to this, I have extensively the mechanistic effects of manuka honey on P. aeruginosa growth, virulence, and biofilm formation.
