Research interests

Microbial Biofilms and their Control, Adaptive Biology and Evolution of Microorganisms, Biofilm-Associated Infection, Microbial Ecology, Environmental Biotechnology, Antimicrobial Resistance (AMR).

Bacteria often switch from a free-living lifestyle to a surface adapted, structured lifestyle known as a biofilm. Biofilms are increasingly recognised as the predominant mode of bacterial growth including within medical, engineered, and environmental contexts. Biofilms are notorious for their resistance to environmental stresses, including antimicrobial compounds. This tolerance often links biofilms with persistent and chronic infection, and provides ideal conditions for the acquisition or evolution of AMR.

My research group aims to understand how biofilms develop and disperse and how they respond to environmental stresses including therapeutic compounds. This approach is providing new technologies and strategies to control biofilms in industrial and medical settings.

Selected findings:

Cell lysis as a feature of biofilm development. We found that subpopulations of biofilm bacteria undergo cell death and lysis as a feature of the Pseudomonas aeruginosa biofilm life cycle. This can contribute to biofilm dispersal, and provides a mechanism for the release of extracellular DNA (eDNA) within biofilms. PubMed ID: 14662353

Role of a new filamentous prophage Pf4 in Pseudomonas aeruginosa biofilm development. We isolated and named this phage, showed that it becomes superinfective to its host during biofilm development, and found that it plays a role in phenotypic diversification of biofilm bacteria. Further work has shown the importance of this phage in the P. aeruginosa biofilm lifecycle and virulence. PubMed IDs: 15547279; 19005496

Nitric oxide-mediated regulation of biofilm dispersal. We discovered that exogenous nitric oxide can act as a signal for the dispersal of bacterial biofilms. Treatment of biofilms with nitric oxide also reduced their resistance to antimicrobial compounds. Much additional work by our group and others’ is now elucidating the nitric oxide and c-di-GMP-mediated signalling pathway, and its exploitation for biofilm control in medical and industrial contexts. PubMed ID: 17050922

An increase in bacterial mutation rate can promote biofilm formation. We showed that strains of Pseudomonas aeruginosa with increased mutation rates (caused by deletion of genes involved in DNA mismatch repair) produced more biofilm biomass in laboratory experiments. PubMed ID: 19606212

Short-term parallel evolution in biofilms. Using next-generation sequencing approaches, including deep sequencing of entire populations of bacterial cells, we showed that reproducible patterns of evolution can occur quickly (<20 generations, a few days of biofilm growth) within biofilms. PubMed IDs: 27190203, 24706926
