Research Interests

    Chronic Infection                    

Chronic infection is the hallmark of cystic fibrosis lung disease. I have a key interest in respiratory pathogens that cause opportunistic infections in cystic fibrosis patients and in more recent years, in vaccine development.  In particular, I focus on Burkholderia cepacia complex.  This is a highly antimicrobial resistant pathogen and effective treatments are challenging.     I also have an interest host responses of epithelial cells, mechanisms of pathogenesis and mechanisms of bacterial adaptation which facilitate chronic colonisation.  We are currently examining the role of stress proteins in chronic colonization and the switch that controls the transition from acute to chronic infection.  We also investigate two other pathogens associated with CF-infections, Pseudomonas aeruginosa and genus Pandoraea. 

As a result of our investigations on mechanisms of attachment of pathogens to lung epithelial cells, we identified a number of bacterial adhesins, which are potential vaccine candidates.   The antigens protect mice against Burkholderia and have potential as novel vaccine antigens.    We have identified vaccine candidates against Burkholderia cepacia complex, Burkholderia pseudomallei and verotoxigenic E. coli
