Our research Antibiotic resistance, bacteriocins, biofilms, quorum sensing, social interactions
What are we interested in? Our focus is on understanding microbial interactions and social behaviors and the implications for virulence, disease and antimicrobial resistance (AMR). Our main study organism is the antibiotic resistant superbug Pseudomonas aeruginosa (Diggle & Whiteley 2020). The CDC has identified P. aeruginosa as a 'serious threat' in healthcare settings. It is also the key pathogen in cystic fibrosis lungs and is commonly isolated from non-healing diabetic wounds.
Biofilms and infection
P. aeruginosa assembles different aggregate types due to an interplay between environmental polymer concentration and cell surface hydrophobicity (Azimi et al. 2021).
