Robyn’s research aims to improve understanding of microbial factors that contribute to the onset, progression and persistence of chronic lung and middle ear infections affecting children. She is specifically interested in understanding how bacteria in complex polymicrobial communities contribute to the onset and progression of chronic mucosal infections.
Her research draws together bacterial, viral and biofilm studies to achieve better understanding of the microbial ecology of chronic respiratory and ear infections. This includes application of OMICs technologies to characterize the structure and function of upper and lower airway bacterial communities. The long-term aim of this research is to find new ways to prevent, diagnose and manage chronic lung and ear infections.
